Chapter 9, Problem 9.20P

Example problem of reheat cycle

In a reheat cycle steam at 550°C expands in an h.p. turbine till it is saturated vapour. It is reheated at constant pressure to 450°C and then expands in a I.p. turbine to 40°C. If the maximum moisture content at turbine exhaust is limited to 10%, find (a) the reheat pressure, (b) the boiler pressure, c) the net specific work output,plss give info as much as possible

Give an Example of a problem on Actual Reheat rankine cycle with complete solution and compare it with a simple rankine cycle with the same given data.

Provide diagram, given, and step by step solution.  A diesel cycle has a compression ratio of 8 and an initial condition of air of 31 degree celsius. If maximum temperature is 1400 degree celsius, find the cycle efficiency.

Q2/Gas turbine unit having heat exchanger with thermal ratio(0.75),ahigh pressure stage turbine drives the compressor and a low pressurestage turbine generate the power. The overall pressure ratio is (5/1) andthe maximum temperature is (1000 o c).The isentropic efficiencies ofcompressor, H.P.T and L.P.T are (0.7),(0.78) and (0.8) respectively andmechanical efficiency of both shafts is (99 %) . Calculate:a- The pressure between turbine stages when the air intake conditionare (1 bar) and (29 oc) b- Thermal efficiency when the mass flow is (30 kg/sec)Cpg= 1.15 kJ/kg.K ɣg=1.33

1. A sample of gas A evaporates over water in a closed system. What is the pressure of gas A In kg/cm2 if the total pressure is 780 torr and water vapor pressure is 1 atm?

in a steam poer cycle the steam suppy is at 15 br and dry and saturated .the condenser pressure is 0.4 bar calculate the carnot and ranking efficiencies of the cycle .neglect pump work

An air conditioning supply fan is operating at and requiring 4.85kW. 600 RPM against is delivering 540m / min at 500PA SP It standard conditions. In order to handle air conditioning load, heavier than originally planned, more air is desired, in order speed SP and to increase flow are the new power?
