Question
The figure illustrates the flow of an ideal fluid through a pipe of circular cross section, with diameters of 1cm and 2cm and with different elevations. Px is the pressure in the pipe, and Vx is the speed of the fluid at locations x = Q,R,S,T, or U.
1)VU is .... VS
2)PR is .... PT
3)PS is .... PQ
4)VT is .... 0.5VU
answers are less, equal, or greater.
Explanation / Answer
1)Velocity at u > Velocity at s
2)Pressure at R > Pressure at T
3)Pressure at S = Pressure at Q
4)Velocity at T = 0.5*Velocity at U
note : velocity increases with increses in area....
and pressure decreases withincrease in velocity...
