Study Notes
Fluid Flow Rate
- The equation (P1 − P2) / 8ηLQ = 1/ π r4 can be used to calculate fluid flow rate (Q).
- P1 and P2 represent the pressures at two points in the fluid flow.
- η represents the fluid viscosity.
- L represents the length of the flow path.
- Q represents the flow rate.
- r represents the radius of the flow path.
Fluid Flow Rate Calculation
- The equation to calculate flow rate can be used by plugging in the radius values for different scenarios and calculating the time it takes for the fluid to flow.
Fluid Flow Rate Calculation Example
- To calculate flow rate, the equation (P1 − P2) / 8ηLQ = 1/ π r4 can be used.
- The flow rate "Q" can be calculated by substituting the given values for pressure, viscosity, length and radius in the equation.
Unit Considerations
- It is important to note that when using the equation for fluid flow rate, it is crucial to ensure that all values are in the same units system.
- If values are given in centimeters, they should remain in centimeters throughout the calculation, no need to convert to meters.
Total Energy Calculations
- The text mentions that the calculation assumes the total energy of the system is known. If the total energy is not specified, further calculations may be required.
