1. Consider the equation F = DP/R. It describes the flow (F) of fluid in a tube in which there is a pressure difference (DP) between the two ends and a resistance (R) to flow. The equation indicates that(2.0 Score )
A.the flow of fluid from point A to point B in a tube depends upon the difference in pressure between A and B.
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 flow for any given pressure difference.
D.the flow of fluid in a tube depends upon the absolute pressure at the beginning of the tube and the greater the resistance to flow in a tube, the greater the flow for any given pressure difference are correct.
E.the flow of fluid from point A to point B in a tube depends upon the difference in pressure between A and B and the greater the resistance to flow in a tube, the greater the flow for any given pressure difference are correct.
