Resistance to Flow Through One-Way and Two-Way Valves is Mainly

Question

Resistance to flow through one-way and two-way valves is mainly determined by:
A) Size of the valve leaflets
B) Dead space volume of the valve body
C) Number and types of pressure taps
D) Tubing connected to the valve

Accepted Answer

The resistance to flow through valves is mainly determined by the size of the valve leaflets, as this determines the cross-sectional area through which fluid can flow. Dead space volume, number and types of pressure taps, and tubing connected to the valve can contribute to resistance but to a lesser extent compared to the size of the valve leaflets.
