A closed well insulated tank contains 10 kg of air at 300 K. An electric motor drives a propeller inside the tank until the temperature of the air has risen to 400 K. How much work had to be done by the motor to raise the air temperature by this amount?
U1= 1.41 kJ/kg
U2= 72.93 kJ/kg
The humidity of air can be determined by use of two different thermometers; a 'dry bulb' thermometer and a 'wet bulb' thermometer. explain how these thermometers can be used to estimate the amount of water vapour in the air.
