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.
pressure of liquid on bottom=density*gravitational force*depth :)
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.
Boiling, a type of phase transition, is the rapid vaporization of a liquid, which typically occurs when a liquid is heated to its boiling point, the temperature at which the vapor pressure of the liquid is equal to the pressure exerted on the liquid by the surrounding environmental pressure.
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)
Area of the container and the mass of the gas or liquid inside.

Ok. there's a fixed ratio for Nitrogen as it expands from liquid to gas. From liquid, it expands 696 times from its boiling point at atmospheric pressure.

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.
The liquid starts boiling
The weight of the liquid is, plus possibly the atmospheric pressure on the top surface of the liquid.
Atmospheric pressure Density of the liquid Gravitional field strength in the area the liquid is in The distance from the surface of the liquid i.e. depth Pressure in a liquid=Atmospheric pressure +(Depth X Gravity strength X Density) There might be more I don't know about

If the liquid is static or moving with a constant velocity, then liquid pressure at a particular level is constant.In case the liquid is in accelerated motion we will get variation in the liquid pressure at a particular level
