Gravitational Constant
The value of gravitational constant below see level at 4500m depth was found to be 9.8295m/s2 and this is maximum after that it decreases...What would be the value of the acceleration due to gravitation at the center of earth?

the gravitation constant again decreases as we go down the 4500m level below the sea level....

Boiler efficency can be increased by incresing the boiler pressure or by the reheating the steam or by the process of regeneration. Another method is that by increasing the mean temperature of heat addition so that boiler efficiency can be inceased.

The main problem which derease the efficiency of boiler are caused by hard water. So the best method to increase the efficiency is to use hardness free water and for that water should be treated properly.
