Question: Create a helical compression spring for a pressure relief valve in a hot water system.

Givens: - Diameter of the valve seat (or disc seat) is 1 inch.

- The valve should begin to open when the pressure is 60 psi (cracking pressure) and must be fully open when the pressure is 85 psi

- The maximum lift of the valve is 1.5 inches.

- The inner diameter of the bonnet (the case around the spring) is 3.5 inches and the bonnet height is 8 inches

- Design the spring for infinite life

- You need to make some design decisions (such as choosing an appropriate spring material, a safety factor, etc.). You can fix the outer diameter of the spring based on the bonnet size. You can find the spring constant from the force required to completely open the valve. The forces can be found by multiplying the pressure by the area of the disc seat.
