A 25-cm circular grill has an emissivity of 0.9. The temperature of the air and surrounding surfaces is 24°C, while the surface temperature of the grill is maintained constant at 130°C. To compute for the Nusselt number of the air flow, what is the exact value of the temperature in °C on which the air properties should be based?

You can neglect radiation at the bottom of the plate; the bottom side of the plate has water flowing underneath it. Often, when dealing with liquids (rather than gases), one can neglect radiation because heat transfer due to convection is so much larger (liquids tend to have higher convection coefficient values than gases).
The outside temperature of a 10 ft² hot insulated pipe is 140 °F and the surrounding atmosphere is 60 °F. The heat loss by free convection and radiation is 13,020 Btu/hr·ft²·°F. How much of the heat loss is due to radiation? Assume the pipe emissivity is approximately 0.9.
The temperature of a tank in the form of liquid nitrogen is -10 ° C. Tank diameter is 16 cm. The amount of heat lost by convection and radiation from the tank to the environment is 65.5 W / m. Calculate the temperature of the environment where the tank is located .h = 4.35 W / m2K, e= 1.

Discuss the relevance of the ideal gas law constants and explain how changes in one variable affectthe others under the condition of a perfect gas. Include molar mass, gas constant, and specific heatcapacities of gases, including the associated equations.
A stream of Air flows over the upper surface of a flat plate having a length of 10 m. Variation of temperatures measurements in the boundary layer is correlated by an expression of the form T = 785 + 50 exp (-712xy), where x and y are in meters and T in K. The thermal conductivity of air is evaluated at the arithmetic mean of the free stream and surface temperatures to be k = 0.03 W/m.K. If the air temperature is equal to 45 C and the temperature of the plate is equal to 105 C. Determine The average convection coefficient for the entire plate. Select one: O a. 98.6 W/m^2.K O b. 78 W/m^2.K O c. 89 W/m^2.K d. 66.2 W/m^2.K
Q1) A polished metal pipe (8 cm) owtside diameter and 350 K temperature at the outer surface is exposed to ambient conditions at 285 K temperature.

A distance was measured with an electronic infrared device, during which the influential weather elements prevailing at the time of measurement were measured at The ends of the measurement line were as follows: temperature at the beginning of the line = 26°C; atmospheric pressure at the beginning of the line 680mb; end of line temperature = 32°C; Atmospheric pressure at the end of the line is 670mb. Calculate the amount of correction to be added to the measured distance, given that the length of the carrier wave is The measurement used is 915nm = m Note: - The correction is calculated from the following relationship: 273 N,(ppnm) = (n, - 1)x10* = (n, - 1X X)x10; (n,-1)x10 = 287.604 +- 273+t760 1.6288 0.0136 +-
