Fluid Flow Concepts Puntos:1 The figure illustrates flow through a pipe with diameters of 1 mm and 2 mm and with different elevations. px is the pressure in the pipe, and vx is the speed of a non-viscous incompressible fluid at locations x = Q,RS,T, or U. 0 D-2 mm Select the correct answers.

Answer 1

a) From the given diagram,

since height is same for both, diameter is lower at u which means velocity is more at u which means pressure is less at u.

Hence Ps is greater than Pu..

b) From the given diagram,

Since diameter is double at R than the diameter at U, hence velcoity will be 2^2 = 4 times at U.

Hence, Vr is lesser than 0.2Vu.

c) From the given diagram,

Since diametre is same and r is at more height hence lesser pressure.

Hence Ps is greater than Pr.
