- A shaft of 0.06-m diameter is heat treated in a gas-fired furnace whose gases is at 1200 K and provide a convection coefficient of 125 W/m² K. If the shaft enters the furnace at 300 K and stays in the furnace. (1) What is the centerline temperature (in K) of the shaft after 900 seconds? (2) What is the value of the dimensionless Fourier number? The shaft material has a density of 7000 kg/m², thermal conductivity of 50 W/m.K, and specific heat capacity 500 J/kg.K. Please show your work and assumptions.arrow_forwardQ) An apple has been put into a freezer at (-13°C) to be cooled. Initially, the apple is at a uniform temperature of 23°C. The convection heat transfer coefficient on its surface is 7 W/m2.°C. Assuming the apple as a sphere having a diameter of 6.5-cm and taking its properties as p = 930 kg/m3, cp = 3010 J/kg-°C, and k = 0.490 W/m°C, determine; (a) the center temperature of the apple in 30 minutes, (b) the actual amount of heat transfer from the apple, and (c) the final equilibrium temperature of the apple. Hint: consider the temperature is a function of location and time.arrow_forwardTwo coaxial cylinders, r1 = 3.5 cm, r2 = 8cm, of equal length (3.5 m) are placed inside a very large room maintined at 350 K.

Oil enters the tube side of a shell-and-tube heat exchanger with a flow rate of 5.04 kg/s (c, = 2.09 kJ/kg-K; p = 900 kg/m3) and it is cooled from 366.5 K to 344.3 K by 2.02 kg/s of water entering at 283.2 K. The overall heat-transfer coefficient U, is 340 W/m2-K. The tubes have an outside diameter of 60.33 mm and inside diameter of 52.50 mm (use outside diameter for surface area, use inside diameter for mass flow rate in tubes). The velocity of the oil is 0.100 m/s. Calculate the number tubes and tube passes if space constraint limits the tube length to be 1.50 m and lesser and shell pass is only 1.

- Steam in a heating system flows through a 1-m long tube whose outer diameter is D1 = 3 cm andwhose walls are maintained at a temperature of Tb = 120 °C. Circular fins (k = 46 W/m. °C) of outer diameter D2 = 6 cm and constant thickness t = 2 mm are attached to the tube, as shown in the figure. The space between the fins is 3 mm, and thus there are 200 fins per meter length of the tube.Heat is transferred to the surrounding air at Tꚙ = 20 °C, with a combined heat transfer coefficient of h = 90 W/m2. °C.
