ANSWER PLEASE
PROBLEM #2 (68 pts.) Steam at 200 psia, 600°F (State 1) enters an adiabatic turbine cperating at steady state with a mass flow rate of 16.5 lbm/min and exits at 15 psia, 240°F (State 2), Neglecting the changes in kinetic and potential energies and assuming the surroundings to be at T.- 537 R. Determine: a) the actual power output, in Btu/min. b) the reversible (or maximum) power output, in Btu/min. c) the rate of exergy destruction, in Btu/min....

2. Ideal Rankine cycle. The condenser pressure is 4 psia. Steam goes into turbine at 1100F and 1300 psia. The mass flow rate of steam is 2,000,000 lb/h. Cooling water from a lake flows through the condenser at 95,000,000 lb/hr and comes into the condenser at 63F. Determine: a) The net power made (BTU/h) b) Rate of heat transfer in the condenser (BTU/h) c) Overall thermal efficiency (%) d) The outlet temperature of the cooling water (F)

steam enters a turbine at 1000 psia and 1000 degrees celsius,
and leaves at 5Psia and 97% quality, the turbine is adiabatic and
the power output is 25000 hp.
Calculate:
1- the work of the turbine ( in btv/lbm)
2- the mass flow rate in lbm/s, if the work of the turbine is
353.399 btv/lbm
3- the inlet diameter, if the mass flow rate is 60 lbm/s
NOTE: inlet velocity ≈ exit velocity =80 ft/s
1hp=2545 btv/hr

Steam enters an adiabatic turbine at 20 MPa and 700° C. Steam leaves the turbine at a temperature of 160° C with a quality of 88%. Determine the mass flow rate of steam necessary to produce 18 MW power output. Neglect the effect of elevation and velocity changes (20) 5. An air standard Otto cycle compresses air from 14.7 psia and 80°F at the beginning of the compression process. It...

Problem 4 In the vapor power cycle shown below, steam (H20) is the working fluid. Saturated vapor enters the turbine at 100 bar and saturated liquid exits the condenser at a pressure of 0.1 bar. The net power output of the cycle, Weycle, is 150 MW. Isentropic efficiency of the turbine and the pump (n (hi-h2)/(h1-h2s), np=(h25-h1)/(h2-h1)) are both 80%. Determine the followings. [30 pts] (a) Thermal efficiency, n (b) Mass flow rate of the steam, m, in kg/s (c)...
