Fluid mechanics An aqueous solution density 1 gcm3 is flowin

Fluid mechanics

An aqueous solution (density 1 g/cm^3) is flowing through a vertically held tube (diameter 1 cm, length 1 m), with the inlet and outlet pressures both atmospheric. The flow is steady, and the flow profiles at the inlet and outlet are identical. How much force is required to hold the tube in place?

Solution

force required to held the pipe = weight of liquid = mg = pvg = 1000*((3.14*.01^2/4))*1*9.81 =.770085 N
