The head in a vessel with vertical sides and a height of 4m at the instant of opening an orifice was 3m and at closing had decreased to 1.5m. Determine the constant head under which on the same time the orifice would discharge the same volume of water. Determine the time to discharge from a head of 3m as it decreased to 1.5m if the diameter of the vessel is 2m and diameter of orifice is 50mm. Assume c = 0.60. Determine the time to empty the container.

A Borda's mouthpiece 150 mm in diameter discharges water under a head of 3 m. Determine the discharge in L/s if under ideal conditions, the coefficients of a Borda's mouthpiece are Cc = 0.5 and Cv = 1.0.

A Borda's mouthpiece 200mm in diameter discharges water a head of 4m. Determine the discharge in liters/sec and the diameter of the jet at the vena contracta. Cv= 0.98, Cc=0.62

On the head side of a hydraulic cylinder, the rod is 1/2 inch in diameter and the piston is 2 inches in diameter. Calculate the force applied while retracting the rod and the speed at which it moves if the operating pressure is 150 psi and the flow rate is 6.5 gpm. Answer is incomplete without units.

Question Water enters the horizontal circular nozzle with the inlet diameter of 5 in. At the inlet section, fluid has uniformly distributed velocity of 20 ft/s and pressure of 85 psi. The water exits from the nozzle into the atmosphere at the outlet section where the uniformly distributed velocity is 100 ft/s. Determine the axial component of the anchoring force required to hold the contraction in place. Answer The axial component of the anchoring force required to hold the contraction in place is lbf.

A pipe with a diameter of 2cm is attached to a garden hose with a nozzle. If the velocity of flow in the pipe is 2ms, what is the velocity of the flow at the nozzle when it is adjusted to have a diameter of 4mm?

The pump shown in the figure below produces a steady flow of 12 gal/s through the nozzle. Determine the nozzle exit diameter, D2, if the exit velocity is to be V₂ = 109 ft/s. D₂ = Pump i Section (1) Section (2) V₂ in

A pipe tapers over 60m from 450mm in diameter to 675mm in diameter. The gauge pressure at the inlet is 75 kN/m2 and the gauge pressure at the outlet is 90 kN/m2. If the centreline of the pipe rises at a gradient of 1 in 80 and the energy loss due to friction is 0.01m per metre length determine the flowrate in the pipeline and the velocity at entry and exit.

A high-pressure washing system's pump supplies 1 gallon of water persecond at 100 psi pressure. The nozzle should be designed so that the static pressureof the water as it exits the nozzle is the same as the atmospheric pressure. If theinside diameter of the hose leading from the pump to the nozzle is 2 in., whatshould the diameter of the nozzle exit be? What will be the velocity of the waterat the exit of the nozzle?

A venturi meter having a throat diameter of 100mm is fitted into a pipeline which has a diameter of 250mm through which water is flowing. The pressure difference between the entry and throat tapping measured by a U-Tube Manometer containing mercury of a relative density of 13.6 and the connections are filled with the water flowing in the pipeline. If the difference of level indicated by the mercury in the U-tube is 0.63m, calculate: The theoretical volumetric flow rate and The actual volumetric flowrate if the coefficient of discharge is 0.9
