An ice chest whose outer dimensions are 30 cm x 40 cm x 40 cm is made of 3-cm-thick Styrofoam (k = 0.033 W/m °C). Initially, the chest is filled with 28 kg of ice at 0°C, and the inner surface temperature of the ice chest can be taken to be 0°C at all times. The heat of fusion of ice at 0°C is 333.7 kJ/kg, and the surrounding ambient air is at 25°C. Disregarding any heat transfer from the 40 cm x 40 cm base of the ice chest, determine how long it will take for the ice in the chest to melt completely if the outer surfaces of the ice chest are at 8°C. T = 25°C Ice chest D 0°C 3 ст 0°C Styrofoam
The interior walls as well the ceiling and the floor of a room are all at Tg = 10 deg C. The room air is continuously circulated, providing an average convection coefficient of 2.6 W m-2 K-1 at an average temperature of T₁ = 28 deg C. If the room measures 5 m X 4 m X 3 m, estimate the rate at which the air is cooling the room (a negative answer will imply the air is heating the room). Enter your answer using two significant digits in kW.
A cylindrical fuel rod of 2 cm in diameter is encased in a concentric tube and cooled by water. The fuel generates heat uniformly at a rate of 150 MW/m3. The convection heat transfer coefficient on the fuel rod is 5000 W/m2∙K, and the average temperature of the cooling water, sufficiently far from the fuel rod, is 70°C. Determine the surface temperature of the fuel rod and discuss whether the value of the given convection heat transfer coefficient on the fuel rod is reasonable.
In a manufacturing facility, 2-in-diameter brassballs (k = 64.1 Btu/h·ft·°F, r = 532 lbm/ft3, and cp =0.092 Btu/lbm·°F) initially at 250°F are quenched in a waterbath at 120°F for a period of 2 min at a rate of 120 ballsper minute. If the convection heat transfer coefficient is42 Btu/h·ft2·°F, determine (a) the temperature of the balls afterquenching and (b) the rate at which heat needs to be removedfrom the water in order to keep its temperature constant at120°F.
The top surface of the passenger car of a train moving at a velocity of 115 km/h is 2.8 m wide and 8 m long. The top surface is absorbing solar radiation at a rate of 380 W/m2 and the temperature of the ambient air is 30°C. Assuming the roof of the car to be perfectly insulated and the radiation heat exchange with the surroundings to be small relative to convection, determine the equilibrium temperature of the top surface of the car. The properties of air at 30°C are (Table A-15) k = 0.02588 W/m⋅°C, v = 1.608 × 10−5 m2/s, and Pr = 0.7282.The equilibrium temperature of the top surface of the car is:
Hot water at an average temperature of 80°C and an average velocity of 1.5 m/s is flowing through a 25-m section of a pipe that has an outer diameter of 5 cm. The pipe extends 2 m in the ambient air above the ground, dips into the ground (k= 1.5 W/m-°C) vertically for 3 m, and continues horizontally at this depth for 20 m more before it enters thenext building. The first section of the pipe is exposed to the ambient air at 8°C with a heat transfer coefficient of 22 W/m2.°C. If the surface of the ground is covered with snow at 0°C, determine: (a) Heat loss from the part of the tube that is on the ground. (b) Heat loss for vertical part of the tube. The shape factor, and the rate of heat loss on the horizontal part that is in the ground. (d) Total rate of heat loss from the hot water. (e) The temperature drop of the hot water as it flows through this 25-m section of the wall.
This problem is for us to practice convection coefficient calculation for internal flow. You will have to design a water heating system that will heat up water flowing at 1 kg/s from 10°C to 40°C. You have to chose from two heated ducts - (a) one with rectangular cross-section of 0.6 mx1.2 m and (b) the other with 15 cm diameter circular pipe. Both ducts are maintained at a constant temperature of 60°C. Assuming that the flow is fully devloped in both cases, compare the length required for the two ducts to reach the deasired water temperature. Comment on whether the fully-developed assumption is justifiable in both cases.
A supply of 50 kg of chicken at 6degC contained in a box is to be frozen to -18degC in a freezer. Determine the amount of heat that needs to be removed. The latent heat of chicken is 247 kJ/kg and its specific heat is 3.32 kJ/kg-degC above freezing and 1.77 kJ/kg-degC below freezing. The freezing temperature of the chicken is -2.8degC
2-m-long, 0.3-cm-diameter electrical wire extends across a room at 15°C, Heat is generated in the wire as a result of resistance heating, and the surface temperature of the wire is measured to be 152°C in steady operation. Also, the voltage drop and electric current through the wire are measured to be 60 V and 1.5 A, respectively. Disregarding any heat transfer by radiation, determine the convection heat transfer coefficient for heat transfer between the outer surface of the wire and the air in the room.
A 5 - m long section of an air heating system of a house passes through anunheated space in the basement, Figure 1. The cross section of the rectangularduct of the heating system is 20 cm x 25 cm. Hot air enters the duct at 100 KPaand 60 oC at an average velocity of 5 m/s. The temperature of the air in the ductdrops to 54 oC as a result of heat loss to the cooling space in the basement.Determine :a) The rate of heat loss from the air in the duct to the basement under steadyconditions. b) The cost of this heat loss per hour if the house is heated by a natural gasfurnace that has an efficiency of 80%, and the cost of the natural gas in thatarea is $1.6/therm (1 therm = 105,500KJ).

A pipe in a manufacturing plant is transporting superheated vapor at a mass flow rate of 0.3 kg/s. The pipe is 10 m long and has an inner diameter of 5 cm and a wall thickness of 6 mm. The pipe has a thermal conductivity of 17 W/m·K, and the inner pipe surface is at a uniform temperature of 120°C. The temperature drop between the inlet and exit of the pipe is 7°C, and the constant pressure specific heat of vapor is 2190 J/kg·°C. If the air temperature in the manufacturing plant is 25°C, determine the heat transfer coefficient as a result of convection between the outer pipe surface and the surrounding air.
