- An ideal gas flows through a horizontal tube at steady state. No heat is added, and no shaft work is done. The cross-sectional area of the tube changes with length and this causes the velocity to change. (a) Derive an equation relating the temperature to the velocity of the gas.(b) If nitrogen at 150 [°C] flows past one section of the tube at the velocity of 2.5 [m/s], what is the temperature at another section where its velocity is 50 [m/s]?

- A creamy must cool 20,000 liters of milk received each day from initial temperature of 32℃ to a final temperature of 1℃ in 6 hours. If refrigeration losses amount 12 percent of the cooling load, what must be the capacity of the refrigerating machine? Note: Specific heat of milk if 3.9 kJ/kg-K and S.G. = 1.05.You, a process design engineer, are tasked to build a powerplant with a net output of 1 MW. First, in an industrial boiler, coal is burned to heat and pressurize 1.6 kg/s of water pumped from an underground reservoir (25 oC, 1 atm) to High Pressure Steam (44 atm, 450 oC). The industrial boiler is insulated, but due to the high temperatures and the nature of the process there are inevitably heat losses. As such, the total heat losses of the whole system is around 20% of the heat from the coal. The High-Pressure Steam, moving at a linear velocity of 70 m/s, is then used to drive a turbine. The low pressure steam from the turbine is used to preheat the boiling water and then released to the atmosphere as saturated steam (100oC and1atm) at a velocity of 10 m/s via an exhaust 10 m above the turbine inlet. How much heat is needed for the powerplant? Use the following values of enthalpy: Water from reservoir 25oC; 1atm H=104.93 kJ/kg High Pressure Steam 450oC; 44atm H=3324.63 kJ/kg Low…Provide a complete given and computation. Include all the decimals. There are received 68,000 kg/h of steam by an ideal regenerated engine, having only one heater, of which the heater receives 15,400 kg/hr the condenser receives the remainder at 0.007 MPa. If the heater pressure is 0.96 MPa, find the state (quality or "SH) of the steam (a) at the heater entrance and (b) at the condenser entrance.
- Draw a simple diagram. If the dry and wet bulb temperatures of moist air are 35 and 26 respectively find the other thermodynamics properties of air from the psychrometric chart.In the following question you may ignore changes in elevation and velocity of the fluid. (a) In a steam power plant liquid water enters the boiler at a temperature of 40°C and exits as wet steam at a pressure of 15 bar with a dryness fraction of 0·95. Find the heat transfer per kg to the steam. (b) The wet steam passes through a superheater and emerges at a pressure of 15 bar and temperature of 300 °C. It then passes through a turbine, generating 400 kW of power as it does so, and comes out as wet steam at a pressure of 1 bar. The mass flow rate is 0·57 kg/s. There is no heat loss from the turbine. (i) Show that the exit specific enthalpy is about 2337 kJ/kg. (ii) Find the dryness fraction of the steam at the turbine exit. (c) Sketch the T-S diagram for the Rankine (steam plant) cycle and describe the processes. Also indicate on the diagram the points corresponding to the inlet and outlet of the boiler, superheater and turbine.Outside air at 30 C drybulb & 25 C wetbulb temperature flowing at a rate of 25,000 liters/min is mix with colder air at 20 C drybulb & 18 C wetbulb temperature flowing at a rate 70,000 liters/min. After mixing , the mxture undergoes sensible heating up to 40 C . Compute the heating needed in kW. Plot the process on the Psychrometric chart and label it completely. Can you upload the chart also?
