Liquid water at 300 kPa and 25°C is heated in a chamber by mixing it with steam at 300 kPa and 200°C as in the figure below. Liquid water enters the chamber at a rate of 3.0 kg/s, and the chamber is estimated to lose heat to the surrounding air at 25°C at a rate of 35 kW. If the mixture leaves the mixing chamber at 300 kPa and 120°C, establish: a. Mass flow rate of the superheated steam, kg/s...

Water at 600ºC, 10 MPa enters the “hot” side of a well-insulated heat exchanger with a flowrate of 0.1 kg/s and exits as saturated liquid. Water enters the “cold” side of the heat exchanger at 10ºC, 100 kPa with a flowrate of 0.5 kg/s. Find (a) the rate of heat transfer (in kW) between the two fluids and (b) the exit temperature of the cold water (in ºC).

1. R134a in a vapor compression heat pump generates 35 kW of heat to a cold room. Saturated vapor enters the compressor at 1.6 bar and saturated liquid exits the condenser at 8 bar. Assuming 75% isentropic efficiency for the compressor, determine: a) Mass flow rate (kg/s) b) Compressor power (kW) c) Heat transfer from the outside d) Coefficient of performance
MATERIAL AND ENERGY BALANCE
a) Superheated steam at 300°C and 5.0 bar absolute is used to heat a counter-currently flowing stream of propylene gas in an adiabatic heat exchanger. The propylene gas enters the heat exchanger at 40°C and 250 kPa and leaves at 250°C. All of the steam condenses and emerge from the heat exchanger as a saturated liquid at the same pressure. i) Taking a basis of 100 mol/s of the feed gas, draw a...

Homework 2 Problem 1: A piston-cylinder device initially contains 0.35-kg steam at 3.5 MPa, superheated by 7.4 C. Now the stream loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200C. Determine (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer when the piston first hits...

Water flowing at a rate of 10 kg/s through 50 tubes in a double-pass shell-and-tube heat exchanger heats air which flows on the shell side. The tubes are bras with outside diameter of 2.6 cm and are 6.7m long. The heat transfer coefficients on the inside and outside tube surfaces are 470 W/m2K and 210 W/m2K, respectively. Air enters the unit at 15°C with a flow rate of 16 kg/s. The entering water temperature is 350K. A) Draw and label...

01: Steam enters the first turbine at 15.0 MPa and 600°C. The pressure in the condenser is 20.0 kPa. While some steam is extracted from the high-pressure turbine at 5 MPa and sent to the closed feedwater heater, the remaining steam is reheated to 600°C. The extracted steam is condensed as saturated liquid at 5.0 MPa and trapped to the open feedwater heater. Some steam is extracted from the lower-pressure turbine at 1.0 MPa and sent to the open feedwater...

The figure shows a schematic of a power plant that has two steam turbines. The water (the working fluid for the plant) leaves the high pressure turbine (HPT) as saturated vapour at 1000 [kPa]. Part of this flow is diverted to an insulated heat exchanger, which we hot airstream to create superheated steam that enters the low pressure turbine (LPT). The air mas flow rate is 19.5 k/s and the air temperature drops from 1100 to 6001 as it goes...
