Chapter 6, Problem 6.93P

Please be very detailed

During an isentropic process of 3 lb/sec of air, the temperature increases from 50 deg F to 290 deg F. Find the work for a nonflow process.

How much entropy is transferred if 200 W of thermal energy are transferred to a heat sink at 300K?

Q2) A piston/cylinder has ammonia at 1600 kPa, 100°C with a volume of 0.1 m3. The piston is loaded with a linear spring and outside ambient is at 20 °C. The ammonia now cools down to 10 °C at which point it has a quality of 10%. Find the work, the heat transfer and the total entropy generation in the process. NH₂

ii. Inside the cylinder-piston is water with at-200C. During isothermal process, 550 kJ of heat is transferred to the water. Due to this, some water evaporated. The change of entropy of water during this process.

A piston with water vapor at a pressure of 300 kPa and a temperature of 175 oC. 20 kg of fluid is compressed up to 950 kPa pressure in the cylinder arrangement. Piston cylinder device to a heat well at 80 oC in order to keep the temperature of the water in it constant. The heat generated during compression is discarded. a) What phase is the water in the first case? In the last case, what phase is the water in? b) Find the entropy change in water by the process. c) From the cylinder, assuming that the process is a reversible process at constant temperature. Calculate the amount of heat absorbed. d) Find the entropy change of the heat well. e) Consider the total entropy change including the piston-cylinder mechanism and the heat indicate whether the transaction is reversible or irreversible when received. f) T (° C) -s (kJ / kgK) and P (Pa) - by specifying the state change saturation curves and values Show in (m³ / kg) diagrams.

I need the solution for this problem pls. Thanks a lot.

1 kg of steam expands isentropically from 2.5 MPa & 300 Degrees Celsius to .95 MPa. Find the final quality and Wn, Ws.

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.
