Two rooms, each a cube 4.0m per side share a 14 Cm thick brick wall. Because of a number of 100 W light bulbs in one room the air is at 30 degree Celsius while in the other room it is 10 degree Celsius. How many of the 100 W bulbs are needed to maintain the temperature difference across the wall?
The air has a dry ball temperature of 40 ° C and a wet bulb temperature of 20 ° C is heated in a heater so that the temperature of the dry ball increases to 90 ° C. The air is then passed through the corn kernels pile to dry. air that comes out of the pile of corn kernels to dry. The air that exits the corn kernels is at a dry bulb temperature of 60 ° C. then this air is passed to the dehumidifier to reduce its RH to 10%. Draw the course of the process of changing the air on the psychometric diagram. The airflow rate through the corn kernels pile and dehumidifier was 6.0 m / s and the pile cross-sectional diameter was 0.5 m.
a. determine the amount of water lost from the pile of corn kernels (in grams of water / second)
b. determine the amount of water lost from the air when passing through the dehumidifier (in grams of water / second)

- An incandescent lightbulb is an inexpensive but highly inefficient device that converts electrical energy into light. It converts about 10 percent of the electrical energy it consumes into light while converting the remaining 90 percent into heat. (A fluorescent lightbulb will give the same amount of light while consuming only one-fourth of the electrical energy, and it will last 10 times longer than an incandescent lightbulb.) The glass bulb of the lamp heats up very quickly as a result of absorbing all that heat and dissipating it to the surroundings by convection and radiation. Consider a 10-cm-diameter 100-W lightbulb cooled by a fan that blows air at 30°C to the bulb at a velocity of 2 m/s. The surrounding surfaces are also at 30°C, and the emissivity of the glass is 0.9. Assuming 10 percent of the energy passes through the glass bulb as light with negligible absorption and the rest of the energy is absorbed and dissipated by the bulb itself, determine the equilibrium temperature…arrow_forwardA heat conducting rod, 0.90 m long, is made of an aluminum section that is 0.10 m long, and an unknown material section that is 0.80 m long.

At 0.0ºC, the rods are each 50.0 cm long and separated by 0.024 cm at their unfastened ends. At what temperature will the rods just come into contact? (Assume the base to which the rods are clamped undergoes a negligibly small thermal expansion.)arrow_forwardA certain car has 14 L of liquid coolant circulating at a temperature of 95 degrees Celsius through the engine’s cooling system. Assume that, in this normal condition, the coolant completely fills the 3.5 L volume of the aluminum radiator and the 10.5 L internal cavities within the aluminum engine. When a car overheats, the radiator, engine, and coolant expand and a small reservoir connected to the radiator catches any resultant coolant overflow. Estimate how much coolant overflows to the reservoir if the system goes from 95 degrees Celsius to 106 degrees Celsius. Model the radiator and engine as hollow shells of aluminum. The coefficient of volume expansion for coolant is 410x10^-6 degrees Celsiusarrow_forward
