During the execution of a reversible nonflow process where the volume changes 

from an initial volume is 0.845 m3

to a final volume of 0.28 m2

and the pressure varies 

as p = -730V + 690 kPaa, where V is in m3

. Determine the work done

Steam flows through an adiabatic turbine at the rate of 100 lb/min with KE = 0

and Q = 0. At entry , its pressure is 175 psia , its volume is 3.16 ft3

/ lb and its internal

energy is 1166.7 BTU / lb. At the exit, its pressure is 0.813 psia, its volume is 328 ft3

/lb

and its internal energy is 854.6 BTU / lb. What horsepower is developed

Suppose that the steel gas tank in your car is completely filled when the temperature is 16 °C. How many gallons will spill out of the 88-Liters tank when the temperature rises to 40 °C?

A football is kicked vertically upward from the ground and a student gazing out of a window sees it coming passed him at 16ft/sec. The window is 30ft above the ground.

liquid ammonia at a temperature of 26 celcius available at the expansion valve, undergoes isenthalpic process until its temperature becomes 2 degree celcius. find the percentage of liquid vaporized while lowing through the expansion valve

a rigid tank holds 4 kg of water at 20 degree Celcius. If 200 kJ of heat is added to this system, what will be the final temperature? how much work is done in this process

an ideal refrigeration cycle is operating between 120 kPa and 1200 kPa. if R134a is the refrigerant, what is the compression work?

An immersion electric heater was put in some water and raises it's temperature from 40°c to 100°c in 6 minutes. After another 25 minutes it is noticed that half of the water has boiled away. Neglecting heat losses to the surrounding, calculate the specific latent heat of vaporisation of water.
