A rectangular electrical heater is attached to a metal sheet. Measurements show

A rectangular electrical heater is attached to a metal sheet. Measurements show the surface temperatures of T1, T2, T3 are 55, 60 and 42 C, respectively. Both sides of the heater and metal sheet are exposed to an environment where h is equal, and T = 23 C. You can neglect the contact resistance. a. Find the value of h. b. Find the value of the volumetric heat generation. c. Draw the sketch of the temperature as a function of the direction of heat dissipation. d. What is the exact location of the maximum temperature in the plate-heater assembly? e. If h = 230 W/m?K, q_dot = 1 x 10' w/m, what is the maximum temperature in the heater? Convection Convection h=unknown h=unknown Tm = 23 C T. = 23 C Electric heater metal th = 10 mm T3
