Pressure at Bottom of Tank Solution

STEP 0: Pre-Calculation Summary

Formula Used

Hydrostatic Pressure = 10*Density of Liquid Stored*(Height of Tank-0.3)
p_hydrostatic = 10*ρ*(H-0.3)
This formula uses 3 Variables

Variables Used

Hydrostatic Pressure - (Measured in Newton per Square Millimeter) - Hydrostatic pressure refers to the pressure that any fluid in a confined space exerts. If fluid is in a container, there will be some pressure on the wall of that container.
Density of Liquid Stored - (Measured in Kilogram per Cubic Meter) - Density of Liquid Stored is a relative measurement of the mass of an object compared against the space that it occupies.
Height of Tank - (Measured in Meter) - Height of tank is the vertical distance from the floor to the top of the tank. The height of a tank can vary depending on the type, size, and purpose of the tank.

STEP 1: Convert Input(s) to Base Unit

Density of Liquid Stored: 0.001 Kilogram per Cubic Meter --> 0.001 Kilogram per Cubic Meter No Conversion Required
Height of Tank: 4000 Millimeter --> 4 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

p_hydrostatic = 10*ρ*(H-0.3) --> 10*0.001*(4-0.3)

Evaluating ... ...

p_hydrostatic = 0.037

STEP 3: Convert Result to Output's Unit

37000 Pascal -->0.037 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

0.037 Newton per Square Millimeter <-- Hydrostatic Pressure

What is Pressure?

Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Various units are used to express pressure. A simple example of pressure may be seen by holding a knife to a piece of fruit. If you hold the flat part of the knife against the fruit, it won't cut the surface. The force is spread out of a large area (low pressure).

How to Calculate Pressure at Bottom of Tank?

Pressure at Bottom of Tank calculator uses Hydrostatic Pressure = 10*Density of Liquid Stored*(Height of Tank-0.3) to calculate the Hydrostatic Pressure, The Pressure at Bottom of Tank formula is defined as pressure a fluid exerts at equilibrium at a certain point in the fluid due to gravity, increases at lower depths as the fluid can exert more force from the liquid above that point. Hydrostatic Pressure is denoted by p_hydrostatic symbol.

How to calculate Pressure at Bottom of Tank using this online calculator? To use this online calculator for Pressure at Bottom of Tank, enter Density of Liquid Stored (ρ) & Height of Tank (H) and hit the calculate button. Here is how the Pressure at Bottom of Tank calculation can be explained with given input values -> 3.7E-8 = 10*0.001*(4-0.3).

FAQ

What is Pressure at Bottom of Tank?

The Pressure at Bottom of Tank formula is defined as pressure a fluid exerts at equilibrium at a certain point in the fluid due to gravity, increases at lower depths as the fluid can exert more force from the liquid above that point and is represented as p_hydrostatic = 10*ρ*(H-0.3) or Hydrostatic Pressure = 10*Density of Liquid Stored*(Height of Tank-0.3). Density of Liquid Stored is a relative measurement of the mass of an object compared against the space that it occupies & Height of tank is the vertical distance from the floor to the top of the tank. The height of a tank can vary depending on the type, size, and purpose of the tank.
