Heat is conducted in the axial direction through a cylinder by heating one end. If the diameter of the cylinder is doubled (but the cylinder material, cylinder length, and the temperatures at both ends of the cylinder are unchanged), how will the heat transfer rate be changed

Air conditioners not only cool air, but dry it as well. suppose that a room in a home measures 5.0m×9.0m×2.4m . if the outdoor temperature is 30 ∘c and the vapor pressure of water in the air is 85 % of the vapor pressure of water at this temperature, what mass of water must be removed from the air each time the volume of air in the room is cycled through the air conditioner? the vapor pressure for water at 30 ∘c is 31.8 torr.
