Question
Which of the following equation below rightly describes the relationship between the flow(Q), resistance & pressure?
| A. |
Q = (P1 – P2) / R or Q = (ΔP) / R |
| B. |
Q = (P1 + P2) / R or Q = (ΔP) / R |
| C. |
Q = (P1 + P2) / R or Q = (ΔP) * R |
| D. |
Q = (P1 + P2) * R or Q = (ΔP) * R |

Correct Answer � A Explanation |
 |
Ans. A. Q = (P1 – P2) / R or Q = (ΔP) / R.
Q= ΔPπr4 / η8L.
- P – Pressure
- r- Radius of the tube.
- η- Viscosity of fluid.
- L- Length of tube
Simplied form for calculating Flow(Q) = (P1 – P2) / R or Q = (ΔP) / R.
