Water flows over a horizontally standing plate. The length of the plate is 1.5 m and its temperature is constant and at 15 ° C. d. The temperature of the water flowing over the plate is 75 ° C and its speed is 0.11 m / sec. According to this, a.) Calculate the speed and temperature boundary layer thickness at the end of the plate. b.) Find the local heat transfer coefficient and heat flux at the end of the plate. c.) Find the average heat transfer coefficient and heat flux at the end of the plate.

Expert Solution

The solutiion is shown below

Qfrom here for a given value of K we can find the value of h

local Heat flux at the end of plate

q= h/(Tw - T p)

q= 191.04 *K /(75-15)

q= 3.184 K

C) The average heat transfer flux is twice of local heat transfer flux

H= 2*h

H= 2* 191.04 K= 382.08K

and

Q = heat flux= 2*q= 6.368* K

Air flows over a 4 meter long flat plate at a velocity of 8 m/s. Using a spreadsheet, calculate the boundary layer thickness and wall shear stress at 0.1 meter intervals along the plate. Do not plot the wall shear stress at x=0. Use a transition Reynolds number of 5 x 10^5 . (You will need to calculate Rex at each location to determine if the laminar or turbulent correlations should be used.) Generate a spreadsheet table that includes columns...

A thin, uniform bar of length L and mass M is suspended horizontally at rest. It is suddenly released and, at the same instant, it is struck a sharp blow vertically upwards at one end – the duration of the impulse is negligibly short.
