Steam (water vapor) enters a stainless steel tube with inner diameter 4cm at 300°C and 60 bar absolute pressure, with a velocity of 8.00 m/s. The steam exits the tube at 300°C and 40 bar absolute pressure. a. Assuming the water vapor behaves as an ideal gas, calculate the steam mass flow rate and the change in kinetic energy (in Watts). b. Using the specific volume values from table B.7, calculate the steam mass flow rate and the change in kinetic energy (in Watts).
The feed to a compressor is superheated steam at 310°C and 40 bar. It enters the compressor at a velocity of 17 m/s. The pipe inlet inside diameter is 0.25 m. The discharging pipe, after the compressor, has a smaller inside diameter and the discharge velocity is 120 m/s. The exit of the compressor is superheated steam at 350°C and 85 bar absolute. Heat loss from the compressor to the surroundings is 3 kW. Determine the compressor horsepower
Air (MW=29 g/mol) at 115.00 kPa and 285.00 is compressed steadily to 600.0 kPa. The mass flow rate of the air is 2.00 kg/s and a heat loss of 32.1 kW occurs during the process. You may assume that changes in kinetic and potential energy are negligible, the temperature of the surroundings is 25 ∘C, and that the CP of air is 3.5 R. Given the compressor operates with a second law (reversible) efficiency of 0.60,calculate the following. What is the actual work interaction term in kW? What is the actual exit temperature of the air in Celcius?
Steam enters a horizontal turbine at 350 lbf/in² absolute, 580°C, and 12 ft/s and is discharged at 110 ft/s and 25°C saturated conditions. The mass flow is 2.5 lbm/s, and the heat losses are 187 Btu/lb of steam. The enthalpies h₁ and h2 are 3.92E7 ft·lbf/slug and 2.74E7 ft·lbf/slug, respectively. If head losses are negligible, how much horsepower does the turbine develop? hp
