A crucible of molten metal at 1800°C is placed on the foundry floor. The foundry man covers it with a metal sheet to reduce heat loss to the room. If the transfer factor, F, between the melt and the sheet is 0.4, and that between the top of the sheet and the room is 0.8, how much will the heat loss to the room be reduced by the sheet if the transfer factor between the uncovered melt and the room had been 0.8?

Could you please tell me whether 717.5 J is correct Answer or not (Don't copy ,Incase if you are unsure just skip it . I am confused with value ∆T ) Question 1: Consider a piston–cylinder device that contains 0.5 kg air. Now, heat is transferred to the air at constant pressure and the air temperature increases by 5°C. Determine the expansion work done during this process.
At a temperature of 21.4°C the hole in a steel plate has an area of 8.80 x 10- m2. You heat the plate until the area of the hole increases to 8.97 x 10- m2, which allows a steel rod to just slip through this hole. What is the final temperature of the plate? The coefficient of linear expansion of steel is 12 × 10-0/°C.
3- Compare the value between the the actual heat transfer rate Qactual for the surface with fins and the surface without fin ? LIsing any program to draw the relationshin between the actual beat transfer
temperature at every interface. Q4: A thin metal plate is insulated on the back and exposed to solar radiation on the front surface. The exposed surface of the plate has an absorptivity of 0.7 for solar radiation. If solar radiation is incident on the plate at a rate of 700 W/m2 and the surrounding air temperature is 10°C, determine the surface temperature of the plate when the heat loss by convection equals the solar energy absorbed by the plate. Take the convection heat transfer coefficient to be 30 W/m2 °C, and disregard any heat loss by radiation.
6-41 The coefficient of performance of a residential heat pump is 1.6. Calculate the heating effect in kJ/s this heat pump will produce when it consumes 2 kW of electrical power.
A furnace wall is to be designed to transmit a maximum heat flux of 220 Btu/hr.ft of wall area. The inside and outside wall temperatures are to be 2200 • F and 320 ° F. Determine the most economical arrangement of bricks measuring (9 in x 4; in x 3 in). If they are made from materials one with ak of 0.44 Btu/hr. ft. ° F and maximum usable temperature of 1700 ° F and other with a k of 0.94 Btu/hr. ft. ° F and a maximum usable temperature of 2400 ° F. Bricks made of each material cost the same amount and may be laid in any manner (but bricks must remain intact, i.e., no partial bricks). After you answer the question, determine the percent increase in heat flux if there are two -in.-diameter steel bolts extending through the wall per square foot of wall are. (k of steel = 22 Btu/hr. ft. F)|
determine the value of AB. Water is to be heated from 20°C to 70°C as it flows through a 40 mm internal diameter and 600 mm long tube. The outer surface of the tube is wrapped with electrical wire which acts as an electrical resistance heater. The heater provides uniform heat flux throughout the surface of the tube. The outer surface of the heater is well insulated. At steady state if the system provides hot water at 0.2475 kg/s, determine the power rating of the resistance heater and the inner surface temperature of the pipe at the exit. Р = 990 kg/m³; k = 0.631 W/(m K); c Pr-4.328 = 4180 J/(kg K); v = 0.66 x 10-6 m²/s:
