Water flows in a pipe that has a 4ft diameter and the following hypothetical velocity distribution. The velocity is maximum at the centerline and decreases linearly with r to a minimum at the pipe wall. If Vmax = 15ft/s and Vmin = 12ft/s what is the discharge in cubic feet per second

Q1: A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a distribution system for potable water. A completely filled and pressurized water tank was found with a small leakage (a hole 5cm in diameter) located on the sidewall of the tank, around 5 meters below the top of the tank. Please calculate the velocity of leakage water that discharges to the normal atmosphere. The dimension of the tank is 20-meter in height and 10-meter in diameter. The gauge pressure of the water tank top is 0.1M Pa. The Bernoulli equation is: P₁/pg + V₁²/2g +h₁ = P₂/pg + V₂²/2g +h₂ Gauge Pressure: 0.1 M Pa 5 meters Leakage velocity?

A room has a volume of 349 m3. An air-conditioning system is to replace the air in this room every 81.5 minutes, using ducts that have a square cross section. Assuming that air can be treated as an incompressible fluid, find the length of a side of the square if the air speed within the ducts is (a) 2.00 m/s and (b) 7.00 m/s.   a:  b:
