1. Steam enters a turbine with an enthalpy of 1292 Btu/lb and leaves with a enthalpy of 1098 Btu/lb. the transferred heat is 13 Btu/lb. what is the work in Btu/min and in hp for a flow of 2 lb/sec? Hint:1 Btu/min = 42.4 hp. 2. A thermodynamic steady flow system receives 4.56 kg/min of a fluid where p1 %3D 137.90 kPa, Vị = 0.0388 7m Vi = 122, and u = 17.16. The fluid leaves the %3D kg' kg system at a boundary where p2 = 551.6 kPa, v2 = 0.193 kl = 183, and ug %3D v2 %3D kg' 52.80 during passage through the system the fluids receives 3,000 of heat. kg Determine the work. Hints: (a) you have a positive heat(Q), (b)your unit in your final answwer is min." 3. In a steady flow apparatus, 135 kJ of work is done by each kg of fluid. The specific volume of the fluid, pressure and speed at the inlet are 0.37 m3 600 kg' 77L kpa, and 16 - respectively. The inlet is 32 m above the floor, and the discharge pipe is at floor level. The discharge conditions are 0.62 , kg 100 kpa, and 270 kg kJ The total heat loss between the inlet and discharge is 9 of fluid. In flowin kg through this apparatus, does the specific internal energy increase or decreas and by how much? Hints: (a)there is a potential energy in this system, (b)yc are looking for the change in specific internal energy(Au). 4. Steam enters a turbine stage with an enthalpy of 3628 2 kJ at 70 kg and leaves t same stage with an enthalpy of 2846 and a velocity of 124 . Calculate kg 7m kJ work done by the steam. Hint: velocity is also the speed.
