Calculate spacing of a prestressed concrete T slab using 12mm diameter of two legged stirrups such that fc is 415, vcw = 1900kn, balance shear is 934×103?

Calculate spacing of a prestressed concrete T slab using 12mm diameter of two legged stirrups such that fc is 415, vcw = 1900kn, balance shear is 934×103? Correct Answer 165kn

fc is 415, vcw = 1900kn, balance shear = 934kn, using 12mm diameter two legged stirrups spacing, sv = (0.87x415x2x113x1900/934×103) = 165mm.
