Question

I need the answer as soon as possible

The average heat transfer coefficient on a thin hot
vertical plate suspended in still air can be
determined from observations of the change in
plate temperature with time as it cools. Assume
the plate temperature to be uniform at any instant
of time and radiation heat exchange with the
surroundings negligible. The ambient temperature
is 25°C, the plate has a total surface area of 0.1
m2 and a mass of 4 kg. The specific heat of the
plate material is 2.5 kJ/kgK. The convective heat
transfer coefficient in W/m2K, at the instant when
the plate temperature is 225°C and the change in
plate temperature with time dT/dt = - 0.02 K/s, is
%3D

Assume a suitable value if any data is found missing. Two cylindrical pipes are to be used to make a medium drive fit. The nominal diameter of the assembly is 200 mm. The outer diameter of the outer pipe is 230 mm and the inner diameter of the inner pipe is 150 mm. Both the inner and outer pipes are made or aluminum. Assume that both the members have dimensions according to the prescribed tolerances for the kind of fit, determine the maximum and the minimum possible tangential stress in the outer cylinder.
