A compressor receives R-410A as saturated vapor R-410A at 400 kPa and brings it to 2000 kPa, 60°C. Then a cooler brings it to saturated liquid at 2000 kPa (see Fig. below). Find the specific compressor work and the specific heat transfer in the cooler? A eccoi = Compressor Compressor section Cooler section

A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350 °C and velocity of 15 m/s. The exit is at 100 kPa, 150 °C and very low velocity (assume zero). Find the specific work (kJ/kg) and the power (kW) produced.

A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350°C and velocity of 15 m/s. The exit is at 100 kPa, x = 1 and very low velocity. Find the specific work and the power produced.

In a spray condenser, find the ratio of circulating water to steam flow if the condenser pressure is (0.06 bar), and the cooling tower cools the water to (15ºC). Assume turbine exhaust at (88%) quality.

A complex flow system expands helium from 1500 K, 1000 kPa to 500 K, 100 kPa. In the process this produces 4595 kJ/kg of work. The process exchanges heat with a reservoir at TR. If the process is reversible, find the unknown reservoir temperature (K). You can work this with either Thermofluids or the equations... Your choice. If equations, Cp=5.19 kJ/kg-K, Cv=3.12 kJ/kg-K, R=2.08 kJ/kg-K. Helium 1500 K 1000 kPa TR q 500 K 100 kPa W=4595 kJ/kg

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

Please help with the correct answer Thermodynamics problem

The turbine section in a jet engine receives gas (assume air) at 1200 K, 800 kPa with an ambient atmosphere at 80 kPa. The turbine is followed by a nozzle open to the atmosphere and all the turbine work drives a compressor receiving air at 85 kPa, 270 K with the same flow rate. Find the turbine exit pressure P₂ so the nozzle has an exit velocity of 800 m/s.

At an isentropic non-flow process of air, the pressure decreases from 62 psia to 17 psia.It has a mass of 0.15 lb and with initial temperature of 275°F. Find the heat transferred,BtuA. 0 B. 100 C. 200 D. 300
