PROBLEMS (Show your Solution/s) Unless indicated otherwise, use gc = 32.174 Ibm.ft./Ibf.s? and g = 32.174 ft./s? or 9.81 m/s2 = 1. If a nonflow process is carried out so that 30 kJ/kg of work is removed while 75 kJ/kg is added as heat, determine the change in internal energy of the fluid. 2. A gas that is contained in a cylinder is made to undergo a constant-pressure expansion from a volume of 0.1 m3 to a volume of 0.4 m². If the piston moves to keep the pressure constant at 400 kPa, determine the work in kilojoules. 3. Two kilograms of a gas receive 200 kJ as heat at constant volume. If the temperature of the gas increases by 100°C, determine the cv of the process. 4. A gallon is a volume measure of 231 in2. Determine the velocity in a pipe 2 in. in diameter when water flows at the rate of 20 gal./min in the pipe. a
