Problem 4. Water flows from a very large tank through a pipe as shown. The dark liquid in the manometer ismercury. The water at the top of the tank, the water at the exit, and the mercury at the top of the manometer legare all exposed to air at atmospheric pressure. Estimate (a) the pressure drop in the pipe, (b) the water velocity inthe pipe, and (c) the volumetric flowrate. For your analysis, assume inviscid flow along a streamline from the topinterface to a location at the center of the pipe just above the manometer tube. Note that based on themanometer reading, there is viscous flow in the pipe between this point and the exit.largetank ofwater4.0 m5.0 cmpipeflow75 cm15 cm

hi please solve this question. please make sure answer is correct
The pipe (0-1-2) shown in the …gure is angled upward at 30 and is …lled with water. The distance from (1) to (2) (along the pipe) is 1.2 m. The manometer liquid is mercury. For part (a), the pipe is capped at location (0) so that the water is stationary in the pipe. What would be the value of h in this case? For part (b), the pipe shown is just a section of a much longer pipe, and water is ‡owing upwards from (0) to (1) to (2). If the pressure loss due to friction from location (1) to location(2) is 20 kPa, what is the value of h in this case?
In flat areas, water towers are used to supply water to houses. Water is pumped into the tower, and then directed from the tower to houses so that when people turn the water on there is water pressure. The top of the tower is vented to the atmosphere. (a) What is the gauge pressure (total pressure minus atmospheric pressure) at each of the two houses? (in Bernoulli's equation, if the water is not running, you can set v = 0 on both sides, and the external pressure in the water tower is just atmospheric pressure). (b) If a faucet is circular with diameter of 2.0 cm, what is the velocity of the water in each house? You can assume that the velocity of water within the tower is negligible.

(1) A simple, vertical U-tube manometer is used to measure the differencebetween two gas pressures.Write down an equation for the pressure difference in terms of the difference inthe level of the fluid in the manometer. Describe briefly, with the help ofdiagrams, two modifications to the basic design which offer greater sensitivity tosmall pressure differences. Give equations for their use. ii) An extractor fan draws air from a room and delivers it to the surroundingsthrough a 5m long circular duct of diameter 0.1m. The friction coefficientfor the duct flow is 0.002. The fan characteristic, relating its total pressurerise, ∆P (Nm-2) to the volume flow rate is: ∆P = 103−7x104Q 2. What is therate of flow through the duct?You may assume that the room and surroundings are both at atmosphericpressure; state and justify any other assumptions you make.

Assume an ideal fluid with mass density of 900kg/cu.m. The pressure and velocity at section 1 are 100kPa and 10 m/s, respectively. The velocity at section 2is 20 m/s.

What must the gauge pressure p be at A if the volume flow rate out of the pipe at point B is 0.0800 m^3/s?
A venturi meter with a throat diameter of 6 cm is fitted in a horizontal pipeline of 12 cm diameter with oil of specific gravity 0.88 flowing from left to the right. The difference in level in the two limbs of a mercury manometer connected to the tapping points read 12 cm and the connecting pipes are filled with the same oil. A. If two pressure gauges are fitted at tapping points, one at the throat and the other in the inlet. Determine the difference between the 2 gage pressure readings in kPa B. Determine the flow in m^3/s neglecting head losses

The water level in a tank is 66 ft above the ground.A hose is connected to the bottom of the tank at the groundlevel and the nozzle at the end of the hose is pointed straightup. The tank cover is airtight, but the pressure over the watersurface is unknown. Determine the minimum tank air pressure (gage) that will cause a water stream from the nozzle torise 90 ft from the ground.
A pump discharges 8000 liters per minute of a certain brine solution (SG=1.20) to an evaporating pond. The intake line is 25cm in diameter and is at the same level as the pump discharge line, which is 15cm in diameter. The pressure at the inlet of the pump is -170mm of mercury. The pressure gage connected to the pipe discharge reads 150 kPa, and its center is 2.0mabove the center of the discharge flange. The vapor pressure of the brine solution is 40mm of Hg. If the pump efficiency is 80%. How much power is required?
