4. A 90° elbow in a horizontal pipe is used to direct water flow upward at a rate of 40 kg/s. The diameter of the entire elbow is 10 cm. The elbow discharges water into the atmosphere, and thus the pressure at the exit is the local atmospheric pressure. The elevation difference between the centers of the exit and the inlet of the elbow is 50 cm. The weight of the elbow and the water in it is considered to be negligible. Determine (a) the gage pressure at the center of the inlet of the elbow and (b) the anchoring force needed to hold the elbow in place. Take the momentum-flux correction factor to be 1.03 at both the inlet and the outlet. Water 40 kg/s 50 cm

BEER with a density of 789 kg/m3 from a non-elevated open reservoir (P1=0 bars) flows before the pump at 0.75 m/s. The beer is pumped at a rate of 15 m/s to a 5 meter elevated tank with a pressure reading of 0.69 Bars. assuming zero Friction losses, Calculate the actual work if the pump's efficiency is just 44%. Calculate the theoretical and actual power in hp for a mass of 100 kg and a time of 1 minute of Beer.

Problem 5: A pressurized tank of water has a 10-cm-diameter nozzle at the bottom, where the liquid discharges to the atmosphere. The liquid level is 2.5 m above the outlet and the tank diameter can be assumed to be much larger than the diameter of the discharge nozzle. The air pressure in the space above the liquid is 250 kPa (absolute) while the atmospheric pressure is 100 kPa. Neglecting frictional effects, determine the rate of discharge (kg/sec) of liquid from the tank when the liquid level is 2.5m Air 250 kPa 25m 10 cm

In the jet impact experiment, water jet impacts on a curved vane in the vertical direction. As shown in the figure below, the exit has an angle with respect to the vertical direction. The distance from the nozzle to the vane surface at the exit is h. The water volume flow rate is measured to be Q, the density of water is p, and the cross section area of the nozzle is A₁. Assume that the flow has reached the steady state. (1) Use the Bernoulli's equation to determine the velocity Vout at the exit of the vane. Assume that friction between water and the curved vane can be neglected. (2) Apply the Reynolds transport theorem to derive the expression of the impact force F, on the curved vane (neglect the jet weight). (3) Under the condition of a fixed volume flow rate Q, determine the maximum impact force Fr,max that can be obtained when the angle varies (e.g. in different vane designs). Va out 9 Ao Vout h

A cylindrical container with a massless and frictionless piston is filled with water up to a height h, as shown in the schematic. What mass m should be placed on the piston so that the water flow rate through the opened valve doubles? Consider that piston area A₁ = 0.05 m², valve area A₂ = A1/8, h = 0.9 m, Pwater = 1000 kg/m³, and g = 9.80 m/s². piston area: A₁ m = ? Т h/5 valve area: A₂

Water flows through a garden hose at a rate of 1 l/s.  The upstream diameter of the hose is 2.5 cm, and the nozzle outlet has a diameter of 1 cm.  Determine the upstream pressure (gage pressure).

A large, open-topped water tank is being filled from above by a 1.0-cm-diameter hose. The water in the hose has a uniform speed of 11 cm/s. Meanwhile, the tank springs a leak at the bottom. The hole has a diameter of 0.70 cm. Determine the equilibrium level heq of the water in the tank, O measured relative to the bottom, if water continues flowing into the tank at the same rate. heq 1.26 X10-3 Incorrect m

If you have a flat tire and need to pump up the tire on your car with a hand pump, what force do you have to apply to the pump handle?  Assume the air pressure in your tire will be 20 lb/in2, that is 1.1 KPa (138,0000 N/m2). Let the air pump have a cross-section that is 5 cm in diameter.      It depends on the weight of the car.     About 270 N when the tire is full, not much when you start pumping on the empty tire.     About 270 N for as long as it takes from the beginning.       Just a few newtons until you are satisfied with how full the tire is because of the hand pump.
