At the bottom of a water storage tank, the pressure is 31.2 lb/in2 . What is the pressure head?

Three types of fluids stack in an open tank as shown in the picture. If the specific gravidties are sg1=1.00, sg2=2.00, sg3=3.00, and h1=1.00 m, h2=1.00 m, h3=1.00 m, calculate the gage pressure at location 4, P4(gage)=_________(kPa)

4. In a condenser containing air and water, the air pressure is 22 kpa absolute. What is the gage pressure in kpa at a point 1.5 m below the water surface

A small pipe 0.60 m long is filled with water and caped ar its end. It is placed in a horizontal position. a. How fast must it be rotated about a vertical axis 0.30 m from one end to produce a maximum pressure of 6.895 Kpa? b. What is the pressure at the other end of the pipe? c. What is the pressure at yhe midpoint of the pipe?

a)Determine the relationship between the air pressure in the tank and the maximum height to which the water fountain can rise above the discharge nozzle.   b)If a water fountain height of 10 mm is desired, what air pressure should be used?

Pressure was found inside a pipe to be 2 psi. What is the pressure head in feet of water? (Specific weight of water is 62.4 lb/ft³) A. 0.032 B. 0.143 C. 3.51 D. 4.62

2. A perfect venturi with the throat diameter of 1.8 inches is placed horizontally in a pipe with a 5 in inside diameter. Eighty 80 lb of water flow through the pipe each second. What is the difference between the pipe and venturi throat static pressure in psi?

A pump delivering 5000 g.p.m. of 60° F. water has a 16-in.-diameter suc- tion pipe and a 14-in. discharge pipe. The suction vacuum gage, which is 3 in.) below the pump centerline, reads 5 in. of mercury (below atmospheric pressure). The discharge gage, which is 18 in. above the pump centerline, reads 10.6 lb. per sq. in. ga. What is the head of the pump? The specific gravity of mercury is 13.6.

A simple rainwater collector used for home garden use is show below. It is comprised of an open-air water tank, a "compliant" or flexible tube, and a valve. To avoid overflow, the valve is set to open when the water in the tank reaches a height of 2m. The valve rests on the ground 3m beneath the tank's base. The outlet of the valve is open to atmosphere. a) Calculate the pressure at the bottom of the tank when the valve automatically opens. Pam = 101 kPa g = 9.81m/s2 H= 2m p = 998kg/m3 H= 1×10.5 Pa s Water Tank Tube (Smooth) h = 3m d = 5cm Valve 1= 4m

To avoid overflow, the valve is set to open when the water in the tank reaches a height of 2m. The valve rests on the ground 3m beneath the tank's base. The outlet of the valve is open to atmosphere. a) Calculate the pressure at the bottom of the tank when the valve automatically opens. b) Calculate the pressure at the valve when it automatically opens. c) Assuming inviscid flow, estimate the average velocity of the water flowing through the tube at the moment when the valve automatically opens. Assume that the tank is very large compared to the tube, so that the velocity of the water at the top of the tank is zero. Assume that the valve provides no resistance to flow when opened. d) Using your answer to part c), calculate the rate of discharge in kg/s when the valve automatically opens. e) Using your answer to part c), estimate…
