Chapter 9, Problem 9.63P

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?

Show given, complete solution, and diagram.  A steam power plant operates on the Rankine Cycle. The steam enters the turbine at 7 Mpa and 550 with a velocity of 30 m/s. It discharges to the condenser at 20kpa with a velocity at 90 m/s. Calculate the net workin kw for a flow of 37.8kg/s.  a. 23.23 Mw       c. 34.22 Mw b. 53.34  Mw     d. 46.54 Mw

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.

Example problem of reheat cycle

A steam plant that could increase the thermal efficiency by using waste heat from the turbune is an example of while that that could use the electical output from the turbine to generate steam to the system is an example of A toy called Drinking bird is an example of (PMM1/PMM2/PMM3/niether of the two) because the power source is (powered by water in the cup/ powered internally my the movement/ none of the option).

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

Explain ideal Rankine cycle with P-V, T-S and h-S plot.
