Calculate the vacuum pressure in kg/cm2 if the absolute reading is 5psia. a. 0.6816kg/cm2    b. 0.6746kg/cm2   c. 0.7027kg/cm2    d. 0.6324kg/cm3

A 90° elbow in a horizontal pipe is used to direct water flow upward at a rate of 47 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 Water 2 1 FRI 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 magnitude of anchoring force needed to hold the elbow in place. The magnitude of anchoring force needed to hold the elbow in place is 438 * N.

A 90° elbow in a horizontal pipe is used to direct water flow upward at a rate of 43 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.
