A 20 degree Brix apple juice is being pumped from an open tank through a 1-in nominal diameter sanitary pipe into a second tank at a higher level. The mass flow rate is 1 kg/s through 30 m of straight pipe with two 90 degree standard elbows and one angle valve. The supply tank maintains a liquid level of 3 m and the apple juice leaves the system at an elevation of 12 m above the floor. Compute the power requirements of the pump.

Given: Juice density is 997.1 kg/m3 and viscosity is 2.1*10-3 Pa.s. Pump efficiency is 60%.

1. What is the effect on the equilibrium in the apple juice market if apple juice becomes less popular and a cheaper robot is used to pick oranges? Make a graph or two graphs to illustrate the change (just focus on the effect of these 2 changes, and make assumptions when needed) (33 points)

Soybean oil at 30 degress Celsius is to be pumped from an open vat through 60...

Soybean oil at 30 degress Celsius is to be pumped from an open vat through 60 m of standard galvanized iron pipe (internal diameter of 9 cm) into the top of a stroage tank that is 17 m above the surface of the vat. The pipeline contains 3 type B elbows and a gate valve. It is desired to pump the oil at 13.7 m^3/hr. 1) How much work head must be added by a pump at this pumping rate?...

Beer is to be pumped from a fermenting vessel to a racking tank at a velocity of 1.5 m/s through a 100 mm ID pipe, having an absolute roughness of 0.05 mm. The total length of the pipe, allowed for fitting and valves is equivalent to 10 m on the suction side of the pump and 60 m on the delivery. The pump is situated at 3 m below the constant level of beer in the fermenting vessel, which is...

Water is being pumped into a leaky inverted conical tank at a rate of 10 m^3/h. The tank has a height of 9 m and the diameter at the top is 6 m. If the water level is rising at a rate of 0.2 m/h when the height of the water is 6 m, how fast is the water leaking out at that time?

Water is being pumped through a horizontal pipe that is 36.0 m long and 13.5 cm...

Water is being pumped through a horizontal pipe that is 36.0 m long and 13.5 cm in diameter. A pump maintains a gauge pressure of 742 Pa at a large open tank at one end of the pipe. The other end of the pipe is open to the air. If this pipe is replaced by a second one of length 9 m and diameter 5.0 cm, what gauge pressure must the pump provide to give the same volume flow rate...

Water at 200 Fahrenheit is pumped from a storage tank at the rate of 50 gallons/minute. The motor for the pump supplies work at the rate of 2 hp. The water goes through a heat exchanger, giving up heat at the rate of 40,000 BTU/minute(Q Net In), and is delivered to a second storage tank at an elevation 50 feet above the first tank. What is the temperature of the water delivered to the second tank?

A rigid tank with a volume of 20 litres initially contains water at 0.1 degree of dryness and a pressure of 175 KPA. A steam disposal Valve is located at the top of the tank. Adding heat and steam by throwing the final case degree of dryness 0.4 and pressure 150 kPa is desired to be made. How much mass is ejected and what is the entropy produced. Heat source temperature 1000 K.
