• Hydrostatic relation

  Problem: An empirical formula relating pressure and density for sea water w/ temperature held constant is: p/pa = (k+1)(/ a)^7 - k where p= pressure, pa = pressure at the surface, k = dimensionless constant,  = density, a = density at the surface

• Flowrate calculations

  You can convert it for other liquids in this way: kv = flow rate x (density/pressure drop)^-2 2) B/ A valve having a flow coefficient (Kv) of 65 operates with oil of relative density 0.85 and a pressure drop of 1.4 bar across the valve.

• What if Boyle's Law focused on internal pressure?

  With internal pressure, we see a very different effect from external pressure, in that pressure and volume BOTH increase (instead of pressure increasing while volume decreases) and density has decreased.

• Density and Rock

  density of fluid=density of H20 @ standard temperature and pressure = 1000 kg/m^3 Note: Standard Temperature and Pressure = Are reference conditions for temperature and pressure that a quantity can be measured.

• Pressure's effect on temperature/density in a adiabatic process

  230121 Pressure's effect on temperature/density in a adiabatic process The pressure is to be raised from atmospheric to 7 psi (4.83 bar). The process is adiabatic, and the volume is constant and unknown.

• Fluid Mechanics: Static and Dynamic Pressures

  What is its dynamic pressure? 5. The static water pressure at point 1 in a pipe is 100 kPa, and the fluid velocity is 2 m/s. At point 2 downstream, the pipe widens and the velocity decreases to 1 m/s. What is the static pressure at that point?

• Bernoulli's Theorem: Perfume Atomizer

  For simplification, we assume that immediately after the bulb is squeezed there is no pressure gradient in the horizontal tube, and that immediately outside the tube, flow ceases and the pressure is atmospheric pressure Po.
