1. The temperature distribution across a wall 0.3m thick at a certain instant of time is T(x) = a + bx + cx2 , where T is in 0C and x in meters, a = 200 0C, b = -200 0C, c = 30 0C/m2

The wall has a thermal conductivity of 1W/mK.

a) On a unit surface area basis, determine the rate of heat transfer into, out of the wall?
b) If cold surface is exposed to a fluid at 100 0C, what is the convective coefficient?

heat the gas and measure the pressure

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

i think the answer would be reserve.
