Steam enters a turbine operating at steady state at 800f
and500lbf/in^2. and leaves at 0.8lbf/in^2. with a quality of93%.
the turbine develops 15,000 hp, and heat transfer from theturbine
to the surroundings occurs at a rate of 2.5*10^6 btu/h. neglecting
kinetic and potential energy changes from inlet to exit, determine
the volumetric flow rate of the steam at the inlet,
inft^3/hour.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
