It's a heat transfer question Consider a long duct constructed with diffuse and gray walls. The width of each wall is 1 m. Heat transfer is from surface 1 to surface 2, while surface 3 is completely insulated and cannot absorb heat (which means 93 = 0). Az, T2 = 700 K, Ey = 0.5 Aj, T = 1000 K, E1 = 0.33 A - Ag, T3, Ez = 0.8 IRI a. Provide a sketch and state your assumptions b....

Note: Please always outline your assumptions, draw a sketch of the problem and provide a detailed solution. Question 4: (70 Marks) To recover some of the waste heat in the exhaust of a gas turbine, a heat exchanger with unmixed fluids is used. Hot exhaust gases, at Thi-425°C, flow through tubes, and the cold intake air flows across these tubes at Tci= 25°C, and Tco-210°C, The heat exchanger is designed with mass flow rates m-c 10 kg/s, heat transfer coefficients...

What is the long term probability of being in state B? What is the long...
A counter-flow heat exchanger is stated to have an overall heat transfer coefficient of 284 W/m2.K when operating at design and clean conditions. Hot fluid enters the tube side at 101°C and exits at 71°C, while cold fluid enters the shell side at 27°C and exits at 42°C. After a period of use, built-up scale in the heat exchanger gives a fouling factor of 0.0004 m2 K/W. The surface area is 93 m². Assume both hot and cold fluids have...
2. (35P) Ashell-and-tube heat exchanger with 1-shell pass and 20-tube passes is used to heat glycerin (Cp = 2480 J/kg) in the shell, with hot water in the tubes. The tubes are thinwalled and have a diameter of 1.5 cm and length of 2 m per pass. The hot water (Cp=4180 J/kg Centers the tubes at 102°C at a rate of 9 kg/s and leaves at 55°C. Overall heat transfer coefficient U=13900 W/m2C. The glycerin enters the shell at 15°C...
