Consider the equation F = ?P/R. It describes the flow (F) of fluid in a tube in which there is a pressure difference (?P) between the two ends and a resistance (R) to flow. Based on this equation, which is a correct conclusion?8-15-2013
A. If both the resistance and the pressure gradient in a tube increase, the flow must also increase.
B. The flow of fluid in a tube depends upon the absolute pressure at the beginning of the tube.
C. The greater the resistance to flow in a tube, the greater the rate of flow for any given pressure difference.
D. The rate of flow in a tube will decrease if the resistance to flow is decreased.
E. 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.
