A closed coil vertical spring-loaded valve is required for a compressed air receiver. The valve is to start opening at a pressure of 1 MPa and must be fully open with a lift of 4 mm at a pressure of 1.2 MPa. The diameter of the port is 25 mm. Assume the allowable shear stress in steel as 480 MPa and shear modulus as 80 GPa. Design a suitable close coiled round section helical spring having squared ground ends. Also specify initial compression and free length of the spring
