The heat transfer rate due to free convection from a vertical surface, 1 m high and 0.6 m wide, quiescent air that is 20 k colder than the surface is known. what is the ratio of the heat transfer rate for that situation to the rate corresponding to a vertical surface, 0.6 m high and 1 m wide, when the quiescent air is 20 k warmer than the surface? neglect heat transfer by radiation and any influence of temperature on the relevant thermophysical properties of air. consider a large vertical plate with a uniform^face temperature of 130 degree c suspended in quiescent at 25 degree c and atmospheric pressure.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
