This code initially states that n=10 and f=n. Once the code enters the while loop, it stays in the while loop until the condition n>1 is not true. n is subtracted by 1 every iteration. This means that f = 10*9*8*7*6*4*3*2*1. With 9,8,7,6,5,4,3,2, and 1 being repeated n values. The disp (f) command displays the value of f after the while loop, which is equal to (n!).

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
