Question

[30 points] Consider the constant diameter (d = 10 cm) 90° elbow as shown in the Figure Q4. The inlet section of the elbow is connected to a horizontal pipe, and the outlet section is used to direct water flow vertically upward at a rate of 35 kg/s. The outlet section is open to atmosphere, and thus the pressure at the outlet section is local atmospheric pressure. The outlet section is at 60 cm higher elevation than the inlet section. The weight of the elbow and the water in it can be considered negligible. $p_{water} = 1000 kg/m^3$. Determine: (a) The gage pressure at the center of the inlet section, (b) The x- and y-components of force needed to hold the elbow in place (by some fixtures or anchoring)
