What two things does the strength of gravity depend upon?
The force of gravity depends on the mass of objects and distance!
How is pressure and density related?
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
