Consider the Equation F = $\Delta$ P/R It Describes the Flow (F)of Fluid in a Tube

question 112

Multiple Choice

Consider the equation F = $\Delta$ P/R. It describes the flow (F) of fluid in a tube in which there is a pressure difference ( $\Delta$ P) between the two ends and a resistance (R) to flow.Based on this equation,which is a correct conclustion?

• 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.
