2. A given BWR channel measures 3.0 m, and heat is added to regions a, b, and c according

to the diagram below (not drawn to scale). The reactor produces a saturated liquid/vapor

mixture at 7.0 MPa. The feedwater is 225°C, the slip ratio is constant, and the recirculation

ratio is 8:1. Determine the nonboiling height.
