Chapter 6, Problem 6.105P

Solve it correctly please. I will rate accordingly

2.A piston cylinder arrangement contains steam at 10MPaa saturated liquid. Heat was transferred isothermally so that the pressure reaches 2MPaa. а. Find the final temperature of the steam. b. Find the change of entropy in kJ/kg if there is no entropy production.

Liquid water at 35 ºF is fed to a boiler operating at 10 bars and is converted at constant pressureto saturated steam. The steam is produced at a steady state flow rate of 600 lbm/hr. Assume thatthe kinetic energy of the liquid entering the boiler is negligible, and that the steam is dischargedfrom the boiler through a 1 ft pipe.a. Calculate ∆Ĥ (in units of Btu/lbm) for this process.b. Calculate the heat input (Btu/hr) to meet the needed saturated steam production rate.

Four kilograms per second of Methane is compressed isentropically from 104.3 kPa, 140 degree Fahrenheit to 440.6 degree Fahrenheit. Assuming that the process is for ideal gas, find:   Final Pressure, torr   Change in entropy   Work, HP

2000 kg cast iron hoisin at 350 degree Celsius is quenched in 4000 kg of water at 15 degree Celsius. Find the amount of heat transferred to the water bath, entropy change for water and cast iron, use the entropy generation to prove that the entire system does not violate the second law of thermodynamics. Water specific heat of 4.18kj/kg.k, cast iron specific heat of 0.42kj/kg.k

I need the answer as soon as possible

W A polytropic process of air from 150 psia, 300 deg F, and 1 ft³ occurs to a final pressure of 20 psia in accordance with pV1.3-C. Determine

The 6. A fluid expands from 3 bar and 150°C to 1 bar in a nozzle. The initial velocity is 90 m/s. isentropic efficiency is likely to be 0.95. Estimate the final velocity assuming the fluid to be steam and air.

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.
