A steam power plant is located in the northern part of the country. Steam in the plant flows steadily through a 0.203-m diameter pipeline from the steam generating unit (SGU) to the steam turbine. At the SGU end, the steam conditions are determined to be P= 4 mPa, t - 400 celsius, h =3,264.9kJ/kg, and specififc volume = 0.121 m3/kg. At the steam turbine end, the conditions are found to be P=3.5 mPa, t = 392 celsius, h = 3,133.9 kJ/kg, specific volume 0.261m3/kg. Heat loss from the pipeline is 6.92kJ/kg. Determine the steam mass flow rate in kg/s.

You are designing a piping system to facilitate the transfer of water from one industrialprocess to the next. You need the water to condense from saturated vapor to saturatedliquid at a constant 1000 kPa as it flows through the piping system. The pipe is to be madeof plain carbon steel with thermal conductivity ? = 60 W m-K⁄ and inner and outer radii?? = 5 cm and ?? = 7 cm, respectively. The thermodynamic property table at the end of thisproblem will be helpful throughout your analysis.a) If the convection coefficient between the steam and inner wall of the pipe is “verylarge”, what is the temperature of the inner pipe wall along its entire length?(Hint: Isobaric phase change is also iso___?)b) The fluid surrounding the pipe has temperature ?∞ = 30°C and the convectioncoefficient from the pipe to this fluid is ℎ = 100 W/m2⋅K. What is the heat transferrate out of the pipe, per unit meter of pipe? You may neglect radiation effects. Usea thermal resistance network in your analysis.c) The…
It is well known that the power consumed by a compressor can be reduced by cooling the gas during compression. Inspired by this, somebody proposes to cool the liquid as it flows through a pump, in order to reduce the power consumption of the pump. Would you support this proposal? Explain.
How is the Reynolds number related to Darcy-Weisbach?
It is common knowledge that the temperature of air rises as it is compressed. An inventor thought about using this high-temperature air to heat buildings. He used a compressor driven by an electric motor. The inventor claims that the compressed hot-air system is 25 percent more efficient than a resistance heating system that provides an equivalent amount of heating. Is this claim valid, or is this just another perpetualmotion machine? Explain.

How is volume flow rate different than velocity? What happens to volume flow rate in areas where fluid pressure is high?
Using EES (or other) software, investigate the effect of the exhaust gas inlet temperature on the rate of heat transfer, the exit temperature of exhaust gases, and the rate of evaporation of water. Let the temperature of exhaust gases vary from 300°C to 600°C. Plot the rate of heat transfer, the exit temperature of exhaust gases, and the rate of evaporation of water as a function of the temperature of the exhaust gases, and discuss the results.

What is the heat transfer rate required to condense the water, cool the water vapor, and cool the air?
The condenser of a steam power plant operates at a pressure of 0.95 psia. The condenser consists of 144 horizontal tubes arranged in a 12 * 12 square array. Steam condenses on the outer surfaces of the tubes whose inner and outer diameters are 1 in and 1.2 in, respectively. If steam is to be condensed at a rate of 6800 lbm/h and the temperature rise of the cooling water is limited to 8°F, determine (a) the rate of heat transfer from the steam to the cooling water and (b) the average velocity of the cooling water through the tubes.
