Three factors affecting flow rate include pressure, fluid temperature, and orifice size. If any of these factors is increased, the flow rate will not increase. True or False?

The flow rate of a fluid through an orifice is influenced by several factors, including pressure, fluid temperature, and orifice size. When any of these factors are increased, the flow rate typically does increase, not remain unchanged.

Increasing pressure, for instance, enhances the driving force that pushes the fluid through the orifice, resulting in a higher flow rate. Elevating fluid temperature can reduce its viscosity, allowing it to flow more easily, thereby increasing the flow rate as well. Likewise, increasing the orifice size enables a greater volume of fluid to pass through per unit of time, which also contributes to a higher flow rate.

Therefore, the assertion that increasing any of these factors would not lead to an increase in flow rate is false. The incorrect understanding of these relationships supports why the answer is classified as false.
