Please help and use the Heisler Charts provided to find the temperature to be able to solve the problem. Also show all steps on how answer was solved. This class is Heat Transfer. Thank you, will also rate the answer. A horizontal copper plate (k= 374 W/m °C, a = 11.23×10-5 m 2 /s) 10 cm thick is initially uniform in temperature at 250 °C. The bottom surface of the plate is insulated. The top surface is suddenly exposed to a fluid stream at 80 °C. The convection heat transfer coefficient is 935 W/m2 °C. Use the Heisler charts (Figure 4-10) to find the temperature at the top surface (Tt) and then use the Heisler charts (Figure 4-7) to find the temperature at the bottom surface (Tb), and the middle of the plate (Tm) after 5 minutes?
