Heat

 

Man its getting hot here. You don’t have to read the papers or listen to the news to confirm that the temperature is rising across the country, and around the world too. But the papers all full of ‘record-breaking’ news, the maximum temperatures recorded so far this year have shattered all time records.

Climate change is usually assessed over years and decades, and 2015 shattered the record set in 2014 for the hottest year seen, in data stretching back to 1850.The Nasa data shows the average global surface temperature in February was 1.35C warmer than the average temperature for the month between 1951-1980, a far bigger margin than ever seen before. The previous record, set just one month earlier in January, was 1.15C above the long-term average for that month. February was the third consecutive month to break the global temperature record, which is calculated by setting the temperature for a particular month against the average temperature from that month between 1951-1980.February was 1.35C above the norm, easily surpassing the 1.14C margin from January of this year, which also set a record.

Temperatures in Bangalore city is now higher than that of Chennai, which was always known for this hotter climate. While driving back home from work, I can feel the hot air coming in , instead of the otherwise cooler breeze. And things are going to get much more complicated, with load shedding power outages coming up soon. And the last insult to this injury is that the water table in the city is also quickly drying up. News reports say Bengaluru will become hotter this summer. And there is drinking water in stock at KRS only for 60 days.

A study conducted by V Balasubramanian, former additional chief secretary of Karnataka, has sounded a warning bell for Bengaluru: If the current rate of groundwater utilisation continues, there will be a major crisis by 2025 when people may have to be evacuated. The state is also facing an increase in pollution of groundwater in many areas. The groundwater in about 12 of the 30 districts in Karnataka is highly polluted, a recent study by the department of mines and geology shows. "Groundwater is highly polluted with excess concentration of fluoride, arsenic, iron, nitrate and salinity due to both anthropogenic and geogenic factors, particularly in the districts of north Karnataka. The quality of water is deteriorating due to the mixing of sewerage through unlined open drains, leakage from cesspits and septic tanks, and contamination from industrial wastes," the report said.

In the month of March, Kerala usually sees a lot of pre­monsoon activity. But this year the pre­monsoon activity has been little subdued. There is hardly any thundershower activity in the region which is evident around this time of the year. Neither the thundershower activity nor the moderate showers of pre­monsoon has showed up in god’s own country. The current temperatures of the state are at scorching high. The temperatures during the day are fairly high. Mornings and late afternoons will see a lot raised temperatures, as the winds will be flowing from the lands to the sea. These winds are hotter as they travel over the land. But then early evenings and nights will see sudden change in winds that will allow the sea breeze to move towards the land. Early evenings and nights will experience a dip in temperature but this dip in temperature can hardly be experienced as the overall humidity level will be high. But later in the night, the reversal of the sea breeze can be experienced; the temperatures will see a rise. The dissonance over the stability of temperature will be observed over the region, with constant high humid levels sticking their heads up in the state.

90s had some great movies !

Non-Karnataka Vehicles Need Not Pay Lifetime Tax

 

The big news and hot topic of discussion today was not the cricket matches, or the looming elections, or the political cacophony, or Mallya’s escape. The big news is the Karnataka High court ruling in favor of owners of vehicles not regsitered in Karnataka. You see, any vehicle with a non-KA number is instant feast for the traffic police. If the vehicle is in Karnataka for more than 30 days, they have to pay lifetime tax. And vehicle taxes of Karnataka is highest in the country ! The high court on Thursday quashed the amendment (to Karnataka Motor Vehicles Taxation) by the state government to collect LTT from the vehicles registered outside the state and plying in the state for more than 30 days.

The court also quashed the demand notices issued by the Regional Transport Offices (RTOs) to owners of several such vehicles to pay the tax. Several non-KA numberplate bearing vehicles were seized by the Transport Department for non-payment of tax and plying in Karnataka beyond 30 days. The state government had implemented the rule by notifying it in the gazette on February 28, 2014.

In the first year of implementing the rule (2014-15), the transport department collected a whopping Rs 40 crore by initiating action against over 4,000 'defaulting' vehicle owners.In the last two years after the rule came into force, RTO managed to collect Rs 100 crore through LTT and penalties.

Road tax on passenger vehicles is the highest in Karnataka, across all price slabs. Overall, road tax is more than 10% in Karnataka, Tamil Nadu, Andhra Pradesh and West Bengal. Rates in northern states, which comprise a high volume market, are between 8% and 4% for cheaper cars and around 8% for mid-segment cars. But as car prices (ex-showroom) rise, road tax rates go up even in states such as Delhi and Rajasthan.

The Primary Function Of Water Towers Is…..to pump Water !

 

I didn’t know this. All these years I used to look up at water towers and say “Why did they have to build them that tall ?” Here in India, water towers are used primarily as…landmarks ! The Koramangala water tank is well known, then there is the Sankey water tank. But today I learned that the reason of building the water reservoir on a tower is to let gravity act on it, and the water pressure thus created will let the water rise up into higher floors in buildings. Look at the diagram:

At first glance, it would be easy to assume that water towers exist to store water. They are, after all, giant above ground vessels filled with anywhere from tens of thousands to millions of gallons of water.

But whether you’re talking about a modest little water tower perched atop an apartment building in New York City or a giant municipal water tower, water storage is not the primary function of the tower (if water storage was the only goal, it would be significantly cheaper to build a reservoir). The primary function of water towers is to pressurize water for distribution. Elevating the water high above the pipes that distribute it throughout the surrounding building or community ensures that hydrostatic pressure, driven by gravity, forces the water down and through the system.

The design helps keep the cost of water distribution lower for two reasons. First, it allows for centralization of pumping and pressurization, and decreases the number of pumping stations needed in the vicinity of the water tower. Second, it allows the water company to pump water up to the tower during off-peak energy times to decrease the expense of running the pumps.
