- #2 Answer only the 2 question.arrow_forwardRequired information A 90° elbow in a horizontal pipe is used to direct water flow upward at a rate of 41 kg/s. Another identical elbow is attached to the existing elbow such that the water flow makes a U-turn as shown in the second figure. 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. Take the momentum-flux correction factor to be 1.03 at both the inlet and the outlet. Take the density of water to be 1000 kg/m³. Water m kg/s L. X Water FR₂ 50 cm FRX 50 cm If another (identical) elbow is attached to the existing elbow so that the fluid makes a U-turn, determine the gage pressure at the center of the inlet of the elbow.

- A manometer is used to measure the pressure difference between points A and B in a pipe as shown. Water flows in the pipe, and the specific gravity of the manometer fluid is 3.0. The distances and manometer deflection are indicated on the figure. Find (a) the pressure differences and (b) the difference in Piezometric Pressure, (c) the difference in Piezometric head. Express both answers in kPa.arrow_forwardQ2) The flow-metering device shown consists of a stagnation probe at station 2 and a static pressure tap at station 1. The velocity at station 2 is 4 times that at station 1. Air with a density of 1.2 kg/m3 flows through the duct. A water manometer is connected between the stagnation probe and the pressure tap, and a deflection of Ah = 13.7 cm is measured. What is the velocity at Vertical station 2?
