Entering Fig. 12–21 with S = 0.135 \ and \ {l}/{d} = 1 \ , \ we \ find \ {P}/{p_{max}} = 0.42. The maximum pressure p_{max} is therefore

p_{max} = \frac{P}{0.42}= \frac{222}{0.42}= 529 psi

With S = 0.135 \ and \ {l}/{d} = 1 , from Fig. 12–22, \theta_{p_{max}}= 18.5^\circ and the terminating position \theta_{p_0} \ is \ 75^\circ .
