The irreversible reaction is carried out in a reactor that initially contains 1.5 m3 of solution with a concentration of 1 kmol of A per cubic meter of solution. A solution containing 0.50 kmol of A/m3 enters the tank at a rate of 10 m3/h and is mixed perfectly with the existing solution. If the resulting product solution leaves the reactor at 5.0 m3/h, obtain an expression for concentration of A as a function of time. The reaction is first order with k

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?
