Question
SOLVE IT IN PAPER AND SCAN IT TO ME PLEASE :)
One Kilogram of air is compressed pctytropically (in a piston-cylinder system) from 100 kPa and 10 degree C to 1 MPa and 150 degree C Calculate the work done. A ngid tank is divided into 2 parts such that the evacuated part is twee as big as the part that is filled with 50 kg of water a: 200 KPa and 25 degree C. The partition is removed and the water expands in to the entire tank The temperature in the tank remains at 25 degree C Determine volume of the tank, the final pressure and heat transferred.
