Estimate the power (left(mathrm{W} / mathrm{m}^{2} ight)) required to maintain a brass plate at (Delta T_{e}=10^{circ} mathrm{C})

Estimate the power \(\left(\mathrm{W} / \mathrm{m}^{2}\right)\) required to maintain a brass plate at \(\Delta T_{e}=10^{\circ} \mathrm{C}\) while boiling saturated water at \(1 \mathrm{~atm}\). What is the power requirement if the water is pressurized to \(10 \mathrm{~atm}\) ? At what fraction of the critical heat flux is the plate operating?
