A vertical pipe of 2.5 m diameter and 25 m length has a pressure head of 6.5 m of water at the upper end. When water flows through the pipe at an average velocity of 5 m/s, the head loss due to friction is 1.3 m. Find the pressure at the lower end of the pipe, when the flow is upward only with neat diagram

We are experimenting with a brake system. Bar AC rests on the spool at B. Find the force P that can be applied to the cord that is wrapped around the smaller radius of the spool. The spool is frictionless. Only consider friction occurring at point B. The coefficient of static friction at B is 0.37. A 250 lb 1211+ -2 ft- -211--111-1 Radius=9 in.. B P C Radius= 15 in.

Problem 5: A fluid flows by gravity down an 8-cm galvanized ironpipe. The pressures at the higher and lower locations are 120 kPaand 140 kPa, respectively. The horizontal distance between thetwo locations is 30 m, and the pipe has a slope of 1-m rise per10 m of run (horizontal distance). For a fluid with a kinematicviscosity of 10-6 m2/s and a density of 900 kg/m3, determinethe flow rate (in m3/s).

Consider water flowing through a water hose of length of 100 ft, diameter of 3/8 inch, and average surface roughness 5-105 ft. The gage pressure at the hose inlet is 40 psi. The hose contains a ball valve which controls the flow rate. Calculate the mass flow rate of water through the hose with the ball valve completely open and with ball valve 2/3 closed. Hint: Determining the friction factor requires an iterative approach - start the iterations by assuming that the friction factor is equal to 0.01 and perform at least 3 iterations.

Determine the velocity and pressure at sections 2 and 3 if water flows steadilythrough the pipe system shown in Figure.

The turbine at C draws a power P kW. If the intake B has a diameter of de mm. The pressure dg(mm) dĄ(mm) at the intake B is Ps kPa and the velocity of the water (density = 1kg/L) at that point is v (m/s).

A pipe has a diameter D and a friction factor f. Assume that f is constant due to a very large reynolds number. By what percent will the pressure drop in the pipe increase if the volume flow is doubled?

Water at 80°F flows from a storage tank through 618 ft of 6-in Schedule 40 steel pipe, as shown in the figure. Taking the energy loss due to friction into account, calculate the required head hin feet above the pipe inlet to produce a volume flow rate of 1.65 ft³/s.
