Question 1:A 90 elbow in a horizontal pipe is used to direct water flow upward at a rate of 40 kg/s. The diameter of the entire elbow is 10 cm. The elbow discharges water Ointo 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. Determine; (a) the gage pressure at the center of the inlet of the elbow. (b) the anchoring force needed to hold the elbow Take the momentum-flux correction factor to be 1.03 50 cm at both the inlet and the outlet. Water 40 kg/s HIELD IMPROVE OFFICE NOTES Assumptions 1 The flow is steady and incompressible. 2 Frictional effects are negligible in the calculation of the pressure drop (so that the Bernoulli equation can be used). 3 The weight of the elbow and the water in it is negligible. 4 The water is discharged to the atmosphere, and thus the gage pressure at the outlet is zero. 5 The momentum-flux correction factor for each inlet and outlet is given to be = 1.03.
