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)

How do you calculate the liquid pressure?
By using a device called manometers.
What is the formula is used to calculate the pressure in a liquid?
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.
What is the relationship between liquid pressure and the depth of a liquid between liquid pressure and density?
pressure of liquid on bottom=density*gravitational force*depth :)
Is the compressed liquid has the same meaning to saturated liquid?
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.
What can a boil be defined as?
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.
What must you know to calculate pressure?
Area of the container and the mass of the gas or liquid inside.

How do you calculate liquid to gas expansion ratio of nitrogen?
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.
What is the relationship between liquid pressure and the depth of a liquid between liquid pressure and density?
pressure of liquid on bottom=density*gravitational force*depth :)
How do you calculate the subcooling in HVAC?
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.
When the vapor pressure of a liquid equals the air pressure in the room what will the liquid do?
The liquid starts boiling
What is the cause of liquid pressure?
The weight of the liquid is, plus possibly the atmospheric pressure on the top surface of the liquid.
Upon what factors does liquid pressure depend?
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

What is the result from investigating liquid pressure at a particular level?
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
