Question 8

(Multiple Choice)

Consider the equation F = ΔP/R.It describes the flow (F)of fluid in a tube in which there is a pressure difference (ΔP)between the two ends and a resistance (R)to flow.Based on this equation,which is a correct conclusion? 8-15-2013


A)The flow of fluid in a tube depends upon the absolute pressure at the beginning of the tube.
B)The rate of fluid flow in a tube will increase if the pressure at the beginning is increased while the pressure at the end of the tube stays the same.
C)The greater the resistance to flow in a tube,the greater the rate of flow for any given pressure difference.
D)If both the resistance and the pressure gradient in a tube increase,the flow must also increase.
E)The rate of flow in a tube will decrease if the resistance to flow is decreased.
