By using a device called manometers.
The formula relating the pressure in a liquid to the depth of the liquid is P = P0 + dgh. P is the pressure, P0 is atmospheric pressure, d is the density of the fluid, g is the acceleration of gravity, and h is height below the surface of the water.
A pressure detector placed in a vessel to measure liquid level uses the principle that the pressure at a specific depth in a liquid is proportional to the height of the liquid above it. By measuring the pressure at the bottom of the vessel, the detector can calculate the liquid level. This method is commonly used in industries such as oil and gas, chemical processing, and wastewater treatment.
pressure of liquid on bottom=density*gravitational force*depth :)
presure = density*V2/2. Where V is your velocity and you density is the density of the moving fluid or the fluid the object in question is moving through. Often pressure is calculated in head which is V2/2g. Where g is gravity(9.81ms-2)
No - compressed liquid is at a pressure above the boiling point pressure of the liquid. A saturated liquid is right at that boiling point. If you try to drop the pressure on a saturated liquid, it will begin to boil. If you start dropping the pressue on a compressed liquid, it will remail a stable liquid unit you have dropped it to the saturation pressure.
Henry's Law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. This means that as the pressure of the gas increases, the solubility of the gas in the liquid also increases. By knowing the partial pressure of the gas and the Henry's Law constant for that specific gas and liquid, one can calculate the solubility of the gas in the liquid.
Area of the container and the mass of the gas or liquid inside.
Liquid force, also known as hydrostatic pressure, can be calculated using the formula: Pressure = density of liquid x gravitational acceleration x height of liquid column. It represents the force exerted by a liquid at a certain depth due to its weight.

Liquid subcooling in a refrigeration system is the temperature difference between the liquid refrigerant's actual temperature and its saturation temperature at the condensing pressure. To calculate the liquid subcooling for R-22, you need to find the saturation temperature at 260 psig using a pressure-temperature chart, and then calculate the temperature difference between this saturation temperature and 108°F.

To calculate subcooling in HVAC, you need to measure the liquid line temperature and pressure. First, convert the pressure into temperature using a temperature-pressure chart. Subtract the liquid line temperature from the converted temperature to calculate the subcooling. Subcooling is important to ensure the liquid refrigerant leaving the condenser is cooler than its saturation point to prevent the formation of flash gas in the metering device.
Liquid pressure depends on the depth of the liquid, the density of the liquid, and the gravitational acceleration acting on the liquid. The pressure increases with depth due to the weight of the liquid above and is directly proportional to the density of the liquid.
The pressure inside the bubbles of a boiling liquid is equivalent to the vapor pressure of the liquid at that particular temperature. As the liquid heats up, the vapor pressure increases until it matches the surrounding atmospheric pressure, causing bubbles to form and the liquid to boil.
