To determine The thermal efficiency of power cycle given in Fig 5.15 whose condenser and boiler pressures are 50 bar and 0.5 bar respectively. Explanation Refer Fig.5.15. Water is used as the operational fluid. Here, boiler acts as the hot reservoir and condenser acts as the cold reservoir. The boiler pressure is 50 bar and the condenser pressure is 0.5 bar . Write the formula for efficiency of the power cycle. η = 1 − T C T H (I) Here, the temperature of the cold reservoir is T C , in Kelvin ( K ) and the temperature of the hot reservoir is T H ,in Kelvin ( K ) . Refer Table A-3, “Properties of Saturated Water (Liquid–Vapor): Pressure Table”. The temperature of water corresponding to the pressure of 0.5 bar and 50 bar is 81.33 ° C and 264 ° C respectively. Conclusion: Substitute 81

First monthly exam Gas dynamics Third stage Q1/Water at 15° C flow through a 300 mm diameter riveted steel pipe, E-3 mm with a head loss of 6 m in 300 m length. Determine the flow rate in pipe. Use moody chart. Q2/ Assume a car's exhaust system can be approximated as 14 ft long and 0.125 ft-diameter cast-iron pipe ( = 0.00085 ft) with the equivalent of (6) regular 90° flanged elbows (KL = 0.3) and a muffler. The muffler acts as a resistor with a loss coefficient of KL= 8.5. Determine the pressure at the beginning of the exhaust system (pl) if the flowrate is 0.10 cfs, and the exhaust has the same properties as air.(p = 1.74 × 10-3 slug/ft³, u= 4.7 x 10-7 lb.s/ft²) Use moody chart (1) MIDAS Kel=0.3 Q3/Liquid ammonia at -20°C is flowing through a 30 m long section of a 5 mm diameter copper tube(e = 1.5 × 10-6 m) at a rate of 0.15 kg/s.
