Water is forced through a contraction causing low pressure T

Water is forced through a contraction causing low pressure. The water is observed to boil at a pressure of -13.01 psi. If atmospheric pressure is 14.70 psi, what is the temperature, in °F, of the water?

the water is start boiling at 212 °F

it means the temperature of water at 14.70psi is 212 °F +239.538 °F =451.53 °F
