Problem 1 •Through a refinery, fuel ethanol is flowing in a pipe at a velocity of 1 m/s and a pressure of 101300 Pa. The refinery needs the ethanol to be at a pressure of 2 atm (202600 Pa) on a lower level. How far must the pipe drop in height in order to achieve this pressure? Assume the velocity does not change. (Hint: Use the Bernoulli equation. The density of ethanol is 789 kg/m3 and gravity g is 9.8 m/s2.Pay attention to units!)
Water at 940 kPakPa , 25∘C∘C enters a 1-mm-diameter horizontal pipe with a steady velocity of 19 m/sm/s . At the exit the pressure drops to 860 kPakPa due to viscous resistance. Assuming steady-state flow, determine the rate of heat transfer (Q˙Q˙) necessary to maintain a constant specific internal energy (uu).

Q.3 A firm produces frozen fruits and vegetables, and a venturimeter is used in this process.In a certain step of the process, the cherries are introduced to the cold air stream at -12oC with a 3 in. pipe connected vertically to the throat of the venturimeter. Venturimeter is connected to a pipe 4 in. in diameter. If the air velocity in the throat is 5 times the terminal velocity of the cherries and the ratio of throat/pipe diameter is 0.6, what should be the flow rate of air? Assume that the density of cherries is 1200 kg/m3 and the average diameters are 12 mm. What should be the lay-out of the pipeline between venturimeter and freeze-dryer to prevent the striking of the cherries to the walls? Is there any settling possibility of the cherries at the exit of the venturimeter?

An engine is tested by means of a water brake at 1000 rpm. The measured torque of the engine is 10000 mN and the water consumption of the brake is 0.5 m^3/s, its inlet temperature being 20 degree C. Calculate the water temperature at exit, assuming that the whole of the engine power is ultimately transformed into heat which is absorbed by the cooling water.
