Utility superheated steam at 1200 °F and 40 bar is available, but the steam cannot drop below 20 bar and 700 °F. Use the steam tables to determine the specific enthalpies of the four streams. The reference for the enthalpies should be water at the triple point. You may interpolate in Tables B6. and B7, and can also use external, automated sources. Determine the amount of superheated steam required to accomplish the evaporation for a superheated steam outlet of 700 °F and 20 bar. Assume no heat losses and use the steam tables to determine enthalpies.arrow_forwardRecitation 11 Problem 1 400 kg/min of steam enters a steam turbine at 300 °C and 80 bar through a 8.5-cm diameter line and exits at 100 °C and 10.0 bar through a 5.5-cm line. The exiting stream may be vapor, liquid, or "wet steam", a mist composed of saturated water vapor and entrained liquid droplets. Find how much power W (kW) is transferred from the turbine to the steam? The answer can be positive or negative. Neglect AE, but not AEK.

The temperature measurements indicate that the average temperature of the outer surface of the steam pipe is 75°C when the ambient temperature is 5°C. There are also light winds in the area at 10 km/h. The emissivity of the outer surface of the pipe is 0.8, and the average temperature of the surfaces surrounding the pipe, including the sky, is estimated to be 0°C. Determine the amount of heat lost from the steam during a 10-h-long work day. Steam is supplied by a gas-fired steam generator that has an efficiency of 80 percent, and the plant pays $1.05/therm of natural gas. If the pipe is insulated and 90 percent of the heat loss is saved, determine the amount of money this facility will save a year as a result of insulating the steam pipes. Assume the plant operates every day of the year for 10 h. State your assumptions.arrow_forward
