The thermal energy generated by a silicon chip increases in proportion to its clock speed. The silicon chip of Problem 10.23 is designed to operate in the nucleate boiling regime at approximately 30% of the critical heat flux. A sudden surge in the chip's clock speed triggers film boiling, after which the clock speed and power dissipation return to their design values.

(a) In which boiling regime does the chip operate after the power dissipation returns to its design value?

(b) To return to the nucleate boiling regime, how much must the clock speed be reduced relative to the design value?
