Aventuri meter (see below) uses the principles of the bernoulli equation to measure the velocity of a flow in a reactor system. consider using a venture flow meter to measure the flow rate of water (at 280ºc) through a pipe 5.0 cm in diameter. the throat of the venturi meter, the narrowest point, has a diameter of 1.0 cm. the pressure difference measured between the two locations is 30 kpa. calculate the volume flow rate of the water, in m3 /s.

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
