A rigid tank of volume 2.3 m3 contains air at 0.21 bar, 290 K. A leak develops and air flows in slowly from the surroundings, which are at 1.1 bar, 312 K. After a while, the tank and its surroundings come to equilibrium. Neglect kinetic and potential energy effects, and assume the air is an ideal gas with constant specific heats evaluated at 300 K.

a. What is the final temperature in the tank, in °C?
b. How much mass has entered the tank, in kg?
c. What is the amount of energy transfer by heat for a control volume that encloses the tank, in kJ?

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
