The pressure difference in a U-tube manometer is calculated using the specific weight of the fluid and the height difference of the liquid column. It provides a direct measurement of pressure differential between two points in a system.
The calculator uses the formula:
Where:
Explanation: The pressure difference is directly proportional to both the specific weight of the fluid and the height difference in the manometer column.
Details: Accurate pressure difference measurement is crucial for fluid system analysis, HVAC systems, hydraulic calculations, and various engineering applications where pressure differentials need to be monitored and controlled.
Tips: Enter specific weight fluid pressure in N/m³ and liquid height difference in meters. Both values must be positive numbers greater than zero.
Q1: What is specific weight fluid pressure?
A: Specific weight is the weight per unit volume of a fluid, typically measured in N/m³. It represents the force exerted by gravity on a unit volume of fluid.
Q2: How does liquid height difference affect pressure measurement?
A: The height difference in the manometer column directly corresponds to the pressure difference - greater height differences indicate larger pressure differentials.
Q3: What are typical units for pressure difference?
A: Pressure difference is commonly measured in Pascals (Pa), though other units like mmHg, inches of water, or psi may be used depending on the application.
Q4: Are there limitations to U-tube manometer measurements?
A: U-tube manometers are limited by the density of the manometric fluid and may not be suitable for very high or very low pressure measurements. They also require visual reading of liquid levels.
Q5: Can this calculator be used for different manometric fluids?
A: Yes, as long as you input the correct specific weight for the particular fluid being used in the manometer.
