Athick plate made of stainless steel is initially at a uniform temperature of 300 c. the surface is suddenly exposed to a coolant at 20 c with a convective surface coefficient of 110 w/m2⋅k. evaluate the temperature after 3 min of elapsed time
(a) at the surface
(b) a depth of 50 mm
work this problem both analytically and numerically.

We convert from degrees Celsius to degrees Kelvin,

Convective temperature coefficient,

For steel we have to,

Given the error equation, then

A)

At x=0

From the tables,

B)

At

At this value

overcharge is the right answer system

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.
