- 3. Drinking water is piped from a water main into a house via a PVC (i.e., smooth) pipe. There is a total of 20 linear feet of 1" diameter pipe between the water main and a point just inside the house that is 10 ft above the water main. This drinking water pipe branches from the water main (K₁ = 0.2), a water meter taps into the pipe (KL = 7), there are two 90° bends (K₁ = 1.5), and finally a (fully open) water shutoff ball valve (K₁ = 0.05) before the point just inside the house. The pipe maintains a flow of 0.05 ft³/s. If the goal is for the gage pressure of the water to be 8640 lb/ft² (aka 60 psi) just inside the house, what must the gage pressure of the water be at the water main?

It has 21 struts and a fixed support at "A". At joint "G", it is applied a force vector with a component of -10 N, along the x-axis direction, and a component of 40 N, along the y-axis direction, as shown in Figure 1. Using the method of joints, calculate the forces for the struts converging at joint "E", i.e. the forces for struts "EA", "EB", "EF", "EG", "ED" and "EH" and specify if the struts are in tension or in compression.
