Problem 4In the figure shown, suppose that the reservoir is open to the atmosphere at the top. The valve is usedto control the flow rate from the reservoir. The head loss across the valve is given as h₁ = 4V²/(2g),where V is the velocity in the pipe. The cross-sectional area of the pipe is 8 cm². The head loss due tofriction in the pipe is negligible. The elevation of the water level in the reservoir above the pipe outlet is9 m. Find the discharge in the pipe (in m³/s). Assume a = 1.0 at all locations.Air underpressureWaterPartly open valve

The water flows from the pipe shown in the figure with a flow rate of 0.025 m3 / s and emerges into the atmosphere as a free jet. Flow is frictionless and gravity effects are negligible. Since the pressure in the section (1) is 150kpa, find the x and y components of the force required to hold the pipe in place. [rsu = 999 kg / m3]
