Chapter 8, Problem 8.34P

A factory generates compressed air from 100 kPa, 17°C by compression to 800 kPa, 500 K, after which it cools in a constant pressure cooler to 300 K, (see Fig. P4.36). Find the specific compressor work and the specific heat transfer in the cooler. 1 2 3 Compressor -w. Compressor section Cooler section

9. Air is expanded from 400 kPa, 600 K in a polytropic process to 150 kPa, 400 K in a piston cylinder arrangement. Find the polytropic exponent n and the work and heat transfer per kg air using constant heat capacity.

please help ne answer this problem with coomplete solution, cancellation of units, and figure. I promise to give high rating. thank you very much   NOTE: Please answer letters: F & G only

Solve it correctly please. I will rate accordingly

Steam enters a turbine at 3500 kPa, 500 C and velocity of 300 m/s and exit at 15 kPa and 25 C. Heat loss is 15 kw. The mass flow rate is 10 kg/s. Find the work output.

Please be very detailed

The number is 9

A condenser (heat exchanger) brings 1 kg/s water flow at 10 kPa quality 95% to saturated liquid at 10 kPa. The cooling is done by lake water at 20 degree Celsius that returns to the lake at 30 degree Celsius. For an insulated condenser, find the flow rate of cooling water.

There are received 25 kg/s of steam at 2.15 MPa, 480°C by a Rankine engine; exhaust occurs at 0.10MPa. find the work of turbine in kJ/s. Insert TS diagram, Use Steam Table SI unit only
