$1\mathrm{.}20$ for a boiling process such as shown in Figure $1\mathrm{.}5$ c $.$ the ambient temperature $T_{}$ in Newton's law of cooling is replaced by the saturation temperature of the fluid $T_{\text{s}\text{e}\text{r}}$ Consider a situation where the heat flux from the hot plate is $q^{\text{'}\text{'}}=20{10}^5\frac{W}{m^2}.$ If the fluid is water at atmosphenc pressure and the convection heat transfer coefficient is $h_w=20{10}^3\frac{W}{m^2}*K,$ determine the upper surface temperature of the plate, $T_{s.}.$ In an effort to minimize the surface temperature, a technician proposes replacing the water with a dielectric fluid whose saturation temperature is $T_{\text{s}\text{a}\text{l},d}=52C.$ If the heat transfer coefficient associated with the dielectric fluid is $h_d=3{10}^3\frac{W}{m^2}*K,$ will the technician's plan work?
