Absolute Pressure at Height h Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absolute pressure = Atmospheric Pressure+Specific weight of liquids*Height Absolute
P_abs = P_atm+y_liquid*h_absolute
This formula uses 4 Variables

Variables Used

Absolute pressure - (Measured in Pascal) - Absolute pressure is the sum of gauge pressure and atmospheric pressure.
Atmospheric Pressure - (Measured in Pascal) - Atmospheric Pressure is the force per unit area exerted into a surface by the weight of the air above that surface in the atmosphere of Earth.
Specific weight of liquids - (Measured in Newton per Cubic Meter) - The Specific weight of liquids is also known as the unit weight, is the weight per unit volume of the liquid. For Example - Specific weight of water on Earth at 4°C is 9.807 kN/m3 or 62.43 lbf/ft3.
Height Absolute - (Measured in Meter) - Height Absolute is the distance between the lowest and highest points of a person/ shape/ object standing upright.

STEP 1: Convert Input(s) to Base Unit

Atmospheric Pressure: 101000 Pascal --> 101000 Pascal No Conversion Required
Specific weight of liquids: 9.85 Newton per Cubic Meter --> 9.85 Newton per Cubic Meter No Conversion Required
Height Absolute: 1123 Centimeter --> 11.23 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_abs = P_atm+y_liquid*h_absolute --> 101000+9.85*11.23

Evaluating ... ...

P_abs = 101110.6155

STEP 3: Convert Result to Output's Unit

101110.6155 Pascal --> No Conversion Required

FINAL ANSWER

101110.6155 ≈ 101110.6 Pascal <-- Absolute pressure

What is absolute pressure?

Absolute pressure is the sum of gauge pressure and atmospheric pressure. Absolute pressure is measured relative to a full vacuum. The Absolute pressure in fluids cannot be negative. Fluids push rather than pull, so the smallest absolute pressure is zero.

How to Calculate Absolute Pressure at Height h?

Absolute Pressure at Height h calculator uses Absolute pressure = Atmospheric Pressure+Specific weight of liquids*Height Absolute to calculate the Absolute pressure, Absolute pressure at height h is the total pressure present at the height h from the surface line. Absolute pressure is denoted by P_abs symbol.

How to calculate Absolute Pressure at Height h using this online calculator? To use this online calculator for Absolute Pressure at Height h, enter Atmospheric Pressure (P_atm), Specific weight of liquids (y_liquid) & Height Absolute (h_absolute) and hit the calculate button. Here is how the Absolute Pressure at Height h calculation can be explained with given input values -> 101110.6 = 101000+9.85*11.23.
