SME 4463/SKMM 3443 Q3. (a) Water is heated from 15oC to 75°C as it flows through a 2.5-cm-internal-diameter, 15-m long tube. The tube is equipped with an electric resistance heater, which provides uniform heating throughout the surface of the tube. The outer surface of the heater is well insulated, so that in steady state operation all the heat generated in the heater is transferred to the water in the tube. If the system is to provide hot water at a...

Water is to be heated from 10 °C to 83 °C as it flows through a 0.015 m-internal-diameter, 13-m-long tube. The tube is equipped with an electric resistance heater, which provides uniform heating throughout the surface of the tube. The outer surface of the heater is well insulated, so that in steady operation all the heat generated in the heater is transferred to the water in the tube. The system provides hot water at a rate of 5 L/min Assumelp...
Water enters through a thick-walled tube having inner and outer diameters of 19 and 38 mm and 20 m long
Water enters through a thick-walled tube having inner and outer diameters of 19 and 38 mm and 20 m long The inlet temperature is Tmi=17℃ and outlet temperature is Tmo = 50°C. The outer surface of the tube is well Insulated, and electrical heating within the wall provides for a uniform generation rate of q = 8X105 W/m3. If the inner surface temperature of the tube Ts = 60 °C at the outlet what is the local convection heat transfer...

Exercise 10 Consider a 2-m-high electric hot water heater that has a diameter of 40 cm and maintains the hot water at 55°C. The tank is located in a small room whose average temperature is 27°C, and the heat transfer coefficients on the inner and outer surfaces of the heater are 50 and 12 W/m2.°C, respectively. The tank is placed in another 46-cm-diameter sheet metal tank of negligible thickness, and the space between the two tanks is filled with foam...
Question Water at an average temperature of 110°C and an average velocity of 3.5 m/s flows through a 5-m-long Beryllium Copper (k-66 w/m.k) tube merge in a boiling water tank. Do NOT ignore the wall...
Question Water at an average temperature of 110°C and an average velocity of 3.5 m/s flows through a 5-m-long Beryllium Copper (k-66 w/m.k) tube merge in a boiling water tank. Do NOT ignore the wall resistance. The inner and outer diameters of the tube are Di 1.0 cm and Do 2 cm, respectively. If the convection heat transfer coefficient at the outer surface of the tube where boiling is taking place is ho- 8400 W/m2.K, a) Determine the overall heat...
