A fan is used to extract 140m3 air per minute from a large room. A circular duct of diameter 0.53 m connects the fan to the room, and the air is exhausted from the fan into the atmosphere through a conical diffuser that increases in diameter from 0.53 m to 0.8 m. A manometer shows that the pressure in the room is sub-atmospheric and the water height differential across the manometer is 6 mm. Neglecting losses, calculate:a. The static and stagnation pressures upstream of the fanb. The static and stagnation pressures downstream of the fanc. The power supplied by the fan to the air[Hint: define the following stations: 1. The room, 2. Immediately upstream of fan, 3. Immediately downstream of fan, 4. The atmosphere]

Problem 2. An engineer helps with the design of a rotating spray for a dishwasher. The spray has 4 identical jets spaced equally around the rim of a disc. Water enters though a hollow shaft and then flows radially out to the jets. The nozzle of the jet has a diameter D of 0.3 cm and makes an angle a = I (3 with the horizontal plane of the disc(See figure). The jets are oriented so that v2r=0. If the total flowrate Q=50 mL/s and the disc has radius R= 7.5 cm, determine the torque in dyne-cm required to keep the disc from rotating. Water jet R.

In a horizontal pipe water flows at a rate of 9.1 L/s. Here, the pipe has two sections, one with a diameter of 10.16 cm and the other with a diameter of 5.08 cm, with a gradual smooth reducing section. In this case, a mercury manometer is used to measure the pressure difference. If friction is negligible how would I find the differential height of mercury between the two sections? If the manometer on the 5.08cm pipe section was replaced with a pitot tube how would the reading change? any help would be deeply appreciated
During a trip to the beach (Patm = 1 atm = 101.3 kPa), a car runs out of gasoline, and it becomes necessary to siphon gas out of the car of a Good Samaritan (see figure). The siphon is a small-diameter hose, and to start the siphon it is necessary to insert one siphon end in the full gas tank, fill the hose with gasoline via suction, and then place the other end in a gas can below the level of the gas tank. The difference in pressure between point 1 (at the free surface of the gasoline in the tank) and point 2 (at the outlet of the tube) causes the liquid to flow from the higher to the lower elevation. Point 2 is located 0.75 m below point 1 in this case, and point 3 is located 2 m above point 1. The siphon diameter is 5 mm, and frictional losses in the siphon are to be disregarded. Determine the minimum time (in seconds) to withdraw 4 L of gasoline from the tank to the can. (Hint: Free surfaces of the gasoline are exposed to ambient air)
