A 100-liter water tank is heated from a 2-kW electrical source. The water is heated up from 20∘C and reached into a terminal temperature of 70∘C. How much is the thermal resistance of the tank? (specific heat of water Cp=4.2kJ/kg)
A computer room located on the second floor of a five-story office building is 10m by 7 m. The exterior wall is 3.5 m high and 10 m long; it is a metal curtain wall (steel backed with 10 mm of insulating board), 75 mm of glass-fiber insulation, and 16 mm of gypsum board. Single-glazed windows make up 30 percent of the exterior wall. The computer and lights in the room operate 24 h/d and have a combined heat release to the space of 2 kw. The indoor temperature is 20 C. (a) If the building is located in Columbus, Ohio, determine the heating load at winter design conditions. (b) What would be the load if the windows were double-glazed?
A 6-m-high and 10-m-wide wall consists of a long 20-cm x 35-cm cross section of horizontal bricks (k = 0.72 W/m · °C) separated by 4-cm-thick plaster layers (k = 0.22 W/m · °C). There are also 3-cm-thick plaster layers on each side of the wall, and a 4-cm-thick rigid foam (k = 0.026 W/m · °C) on the inner side of the wall. The indoor and the outdoor temperatures are 25°C and -2°C, and the convection heat transfer coefficients on the inner and the outer sides are h1 = 12 W/m2 · °C and h2 = 20 W/m2 · °C, respectively. Assuming one-dimensional heat transfer and disregarding radiation, determine the rate of heat transfer through the wall.
Q-2/ An office room has an area of 7*5 square meter and 4m height, this room is heated by the radiator of a steam-heating system. The steam radiator transfers heat at a rate of 10 MJ/h, while a 100-W fan is used to distribute the warm air in the room. During this process, the rate of heat loss from the room is estimated to be about 5 MJ/h. If the initial temperature of the room air is 15°C. Determine; how long it will take for the air temperature to rise to 25°C. Assume constant specific heats at room temperature and the parametric pressure is I bar.

An open cylinder of air has a radius of 38.0 cm and a height of 50.0 cm, as shown in figure (a). 50.0 cm The air pressure is 1.00 atm and the temperature is 13.5°C. A 25.0 kg piston is then lowered onto the cylinder, forming an airtight seal, as shown in figure (b). The air inside is compressed until the piston reaches equilibrium (mechanical and thermal), and at this point the piston is a height h; from the bottom of the cylinder. Lastly, a 27.5 kg dog steps onto the piston, and the air in the cylinder again compresses, as show in figure (c). After reaching equilibrium, the air inside is again at 13.5°C, and the height of the piston decreases a distance Ah as shown. (a) What is the distance Ah (in mm) that the piston moves when the dog is on it? mm (b) To what temperature (in °C) should the gas be warmed to raise the piston and the dog back to h;? °C
