Water 5 cm Mercury

Pro er hydrant nozzle in Fig. 1 has inlet and outlet diameters, D₁ = 8 cm and D₂ 1.0 cm. Water at 20°C flows through the nozzle at 0.001 m³/s and exits to the atmosphere. The atmospheric pressure is 101.3 KPa. Neglect the weight of the piping and nozzle. Compute: a) The exit fluid velocity, V2, ( b) The inlet pressure, Pl c) The horizontal force which must be resisted by the = flange bolts S d) The moment acting on the flange neglect the weight of the hydrant and water 10 m 8 cm Fig. 1: Water hydrant 1

An engineer is designing a cooling jet for a manufacturing process that requires water at 60 °F to be discharged from the nozzle shown below at a rate of 81 gallons/minute. (a) What gage pressuren psi) at Point A is required to produce the desired flowrate? (b) After initial testing, it was determined that air should be used instead of water for the cooling process. However, the engineer is concerned that compressibility could affect performance. Explain how you would modify the Bernoulli equation to account for the effect of air being a compressible fluid. A = 1.0 in.² -A=4.0 in.2

Example(1) Consider the water siphon shown in Fig. below. Assuming that Bernoulli's equation is valid, (a) find an expression for the velocity V2 exiting the siphon tube. (b) If the tube is 1 cm in diameter and z = 60 cm, z2 =25 cm, estimate the flow rate in m²/s. Estimate the pressure at point(3) if 23=90cw z =0---- V2 НОНЕWORК Estimate the pressure at point (3 ) if Z3= 90cm.

Two water tanks, each with base area of 1 ft2, are connectedby a 0.5-in-diameter long-radius nozzle as in Fig. .If h = 1 ft as shown for t = 0, estimate the time for h(t) todrop to 0.25 ft.

Using the figure depicted below, perform the following: (a) Calculate the minimum height h at which cavitation occurs. Indicate on the figure where the cavitation occurs. (b) Calculate the volume flowrate (in m³/s) if h = 25 cm. Be sure to state all assumptions. Note that section 2 opens to atmosphere. D1 = 5 cm h D2 = 10 cm Free Jet (1) 2 Water at 20°C

What is the total force acting on a 90 degrees pipe bend if the flow pressure is 3 x105 Pa, the flowrate is 0.1m3/s and the specific gravity of the fluid is 0.7. The pipe diameter is 10cm and the weight of the fluid can be neglected (remember to consider both force components).

Having trouble with this problem. Please include your assumptions, explanation, and any sketches. Any help would be appreciated!

A necked-down section in a pipe flow, called a venturi,develops a low throat pressure that can aspirate fluidupward from a reservoir, as in Fig. UsingBernoulli’s equation with no losses, derive an expressionfor the velocity V 1 that is just sufficient to bring the reservoirfl uid into the throat.

Could i please have the asnwers and workings out to the attached question.
