5) Oil (S.G=0.9) flows enters the pipe shown through the bottom inlet at a rate of 0.25 m/min and is discharged to at P. - 76 kPa the nozzle outlet at the top. The pipe has a diameter Di = 40 mm at the entrance and a diameter D2 = 20 mm at the exit. If P. = 76 kPa, P2 =20 kPa, and the weight the oil and the piping is negligible, what is the reaction moment at flange...

Water is flowing through a 10-cm-diameter water pipe at a rate of 0.1 m/s. Then, a diffuser with an outlet diameter of 20 cm is bolted to the pipe in order to slow down water as it exits the diffuser to atmospheric pressure, as shown in the given figure. Disregarding frictional effects, determine the force exerted on the bolts due to the water flow. Take the density of water to be 1000 kg/m3 -t- d 10 cmm D = 20...

1 (a) A steady stream of water jet discharges from the nozzle with a uniform velocity of 10 m/s at angle 60° as shown in Figure 1. The jet strikes a horizontal plate 2 m above the nozzle exit. Upon impact, part of the flow is guided towards the left while the remainder towards the right, and the plate is suspended in the air. The weight of the plate is 25 N. Assume frictionless flow along the plate and weight...

Water at 60 °F flows through the elbow as shown below and is then injected to the atmosphere through a nozzle (on a horizontal plane). The pipe diameter is Di = 4 in. while the diameter of the exit of the nozzle is D2 = 1 in. At a flow rate of Q = 245 gpm, the gage pressure at the section (1) where the flange locates is Pi = 34 psig. Neglect the weight of the water and elbow,...

Q2 Water flows at a rate of 0.08 m''min through a flanged tap with a partially closed gate valve spigot (Fig. Q2). The inner diameter of the pipe at the inlet and outlet is 2 cm and 1.5 cm respectively, and the gauge pressure of the water at inlet is measured to be 90 kPa. The pressure at outlet from the tap is atmospheric. The total mass of the tap assembly plus the water within it is 5.8 kg. (a)...

Water is flowing through a 10-cm diameter water pipe at a rate
of 0.2 m^3/s. Now a diffuser with an outlet diameter of 20 cm is
bolted to the pipe in order to slow down water that exits into the
atmosphere, as shown. Disregarding frictional effects, determine
the force exerted on the flange due to the water flow. Density of
water = 1,000 kg/m^3.
