4. A 10 lbm is drop on a 5 kgm piston with a face area of 800 cm² causing the cylinder to decrease in volume and produced a 2KW of Work with 4kgs/hr of gas exiting the fan and heat deflection of 0.5 KJ/Kg. Consider that the atmospheric pressure is 100 KPa, determine the change in internal energy, in KJ/Kg. Neglect the friction between the piston and the cylinder surface. 10 lbm 0.3m 0.5 m WFan
