1. A plate is placed in a large vacuum chamber to control its cooling rate. To prevent cracking, the temperature gradient in the plate cannot exceed 15 K/mm at any point during cooling. The plate is initially at 900 K with an emissivity of 0.8 and thermal conductivity of 1.5 W/mK. Assume that one of the surface of the plate is insulated and the other is exposed to the chamber, and the chamber walls are considered as...

An insulating wall is composed of 10 cm of a material having an thermal conductivity of 5 W/m.K, and an unknown thickness of cork, which has a thermal conductivity of 0.045 W/m.K. How thick must the cork be if the heat losses through the wall are to be less than 10W/m2 when the inside temperature is 20degree C and it's -20degree C outside? Water flows through...

Supplemental Problem 2.003 A large plate of thickness 2L is at a uniform temperature of Tỉ-190°C, when it is suddenly quenched by dipping it in a liquid bath of temperature To Heat transfer to the liquid is characterized by the convection coefficient h. Assume x = 0 corresponds to the midplane of the wall -20°C (a) If h = 100 w/m2, K, what is the heat flux atx = L and t = 0?...

Problem 3 (60 Points). A 1-2 shell-and-tube heat exchanger must be designed to heat 2.5 kg/s of water from 15 to 85°C. The heating is to be accomplished by passing hot engine oil at a rate of 5.2 kg/s, which is available at 160°C, through the shell side of the exchanger. The oil is known to provide an average convection coefficient of 400 W/m2K on the outside of the tubes. Ten tubes passes the water through the shell....

Can you please help me with this question. Much appreciated. So
I have a sample code, but we need to change the code in a way that
fits the problem.
A planar slab of material is initially at a temperature of 300 K. At the time t=0, microwave radiation is directed at the material, leading to internal heat generation that is uniform within the material. The sides of the slab experience negligible heat losses and a water bath maintains the...

Heat Transfer
Problems 1. A window pane (1/8 inch thick) in an old house owned by a professor is 3 ft. by 4 ft. He likes to be warm in the winter so the inside temperature is kept at 70 °F even when the outside temperature is 10 •F. For this problem assume the inside and outside temperatures are for the window surface. How much heat is transferred through the window (k=.54 BTU/hr ft ° F)? 2. A small heated...
