A safety valve spring having 9 and 1/2 coils has the ends squared and ground. The outside diameter of the coil is 115 mm and the wire is 13 mm. It has a free length of 203 mm. The length of which this spring must be initially compressed to hold a boiler pressure of 1.38 MPa on the seat of 32 mm diameter. Modulus of rigidity is taken as G=80GN/m2. a. Find the force acting on the valve set. b. Determine the mean diameter c. Determine the spring index d. Find the spring deflection e. Find the operating length f. Calculate the solid length g. Calculate the deflection of solid length h. Compute the solid force i. Compute the Wahl factor
