To explain this we need to consider two major equationsLet us take1. Bernoulli's equation:P + (Rho)gy + (1/2)(Rho)v^2 const.2.Continuity equation:Which is to maintain constant flow rateQA1v1 A2v2Considering flow is happening through a tapering pipe.P pressureRho densityg gravityy heightQ Flow rate (Kg/cu.metre)A1 area of cross-section-1A2 area of cross-section-2v1 velocity at cross-section-1v2 velocity at cross-section-2Section 1 Larger than Section 2So when flow happens from section 1 to section 2 the area is decresing so the velocity will increase to maintain the constant flow rate by continuity equation.So if you take Bernoulli's equation, to maintain constant value at one side the datum/height or the pressure has to be increased.So Area decreases-->Velocity will increase-->Pressure increases.So velocity and Pressure are inversely proportional unless the Datum/Height is same.Hope this solves your query
Pressure and density are related by volume. P=nRT/V is the ideal gas law, where P is pressure, n is the number of moles of gas, R is the ideal gas constant, T is the temperature, and V is the volume. Density is defined as mass divided by the volume. So, the ideal gas law can be written P=nRTd/m, where d is the density of the gas and m is the mass of the gas.
Higher pressure results in higher density, lower pressure results in lower density.
For example, suppose you have a set volume or container you are putting gas into (i.e. increasing the pressure in the container). The more gas you put in, the greater the mass is contained in that same volume. This means the density has increased.
The relation is that as a fluid (gas or liquid) is denser it ways more. This will make each unit of space have more weight on it which cause more pressure per unit

It doesnt real ate
Water pressure = height (depth) * density of substance * gravitational field strength

At a given temperature, the higher the air density, the higher the air pressure.
The relation between density and pressure can be understood well with the help of the following derivation. Force = Mass x Acceleration →1 Pressure = Force / Area » Force = Pressure x Area →2 Equating 1 & 2 Pressure x Area = Mass x Acceleration Pressure = Mass x Acceleration / Area →3 Density = Mass / Volume » Mass = Density x Volume Eqn. 3 Becomes Pressure = Density x Volume x Acceleration / Area →4 i.e., Pressure is directly proportional to density.The relationship between density and temperature is the higher the temperature, the less the density.
will density of water is equal to density of steam at high pressures and temperatures
Density = mass/volume so it is related to mass and volume. And Volume is related to temperature and pressure, so it is related to those as well.

As air pressure pressure decreases with altitude, so does the densite of air.
As air pressure pressure decreases with altitude, so does the densite of air.
Water pressure = height (depth) * density of substance * gravitational field strength
I assume you mean dansity of a fluid because fluid density changing proportionally to temperature and to pressure change by the equation:ρ1 = [ ρ0 / (1 + β (t1 - t0)) ] / [1 - (p1 - p0) / E]Check out the website in the related link
hey!um why is this not giving me an answer?jk. i no y!

Air has both density and pressure.
Pressure affects the density of air by increase of pressure increases the density
Scroll down to related links and look at "Density of air - Wikipedia" and "Atmospheric pressure - Wikipedia". The density of air is the mass per unit volume of Earth's atmosphere. Air density decreases with increasing altitude, as does air pressure. Air pressure (N/m² = Pa) is a column of air pushing on top of you. If you think of a stack of books, then the bottom has the greatest pressure and the top has the least.
It is related by the grams that are measured by density
