At location A the velocity is 1.5 m/s and the pressure is 138 kN/m2. If the pipe tapers gradually from 150mm diameter at A to 100mm diameter at location B, determine the pressure of the water at B, assuming there is no loss of energy.arrow_forward2. A horizontal nozzle discharges 0.01 m³/s of water into the air. The supply pipe's diameter (d = 40 mm) is twice as large as the nozzle diameter (dB = 20 mm). The nozzle is held in place by a hinge mechanism. Determine the magnitude and direction of the reaction force at the hinge, if the gauge pressure at A is 500 000 N/m2. Assume the weight supported by hinge is negligible. Ans.: Fr= 614 N, 0 = 26.6⁰. FA da 8 = 60° 10arrow_forward

- A uniform tube is used to siphon water from the large tank. If the pressure on the outside of the tube (the atmospheric pressure) is more than 20 kPa greater than the pressure within the tube, the tube will collapse. By using Bernoulli's equation, determine the minimum value of h allowed without the siphon collapsing. The density of water is 1000 kg/m3. Hint: Since the tube is uniform the flow speed in it is constant. The exiting flow from the tube is treated as free jet. 2 m V SARA 1 4 marrow_forwardThe gauge pressure of water at AA is 150.5 kPakPa.
