the pressure exerted by a incompressible fluid (water ) at rest is known as Hydrostatic pressure
Hydro static pressure is the pressure exerted by an incompressible fluid (water ) at a given point, due to the weight of the fluid above it.
the formula for Hydrostatic pressure is P = rho gh
the pressure exerted on the object by the atmospheric is called atmospheric pressure
hence, option (b) is correct answer
Indicates differences between; Hydrostatic pressure and atmospheric pressure. a) Hydrostatic pressure is the pressure on an...
Tire gauges measure the difference between the absolute tire pressure and atmospheric pressure; such that gauge pressure [Pgauge] equals absolute tire pressure [Ptie] minus atmospheric pressure [Patmol; such that tire-Patmo Determine the following: Before a trip, a driver checked gauge pressure at 27.0 C and found it to be 29.3 psi. Eight hours later, it was 39.3 psi. If atmospheric pressure was 14.2 psi, at what temperature in ° C was the air inside the tire after 8 hours of...

4 of 4 3. The formation of a bubble indicates that there is excess pressure AP inside the bubble above the atmospheric pressure. For a bubble of radius R having a surface tension Os, the excess pressure AP is given by: ΔΡ = 205 R a. Draw a free-body diagram of half a bubble indicating the force balance (4 marks) b. Derive the above equation (4 marks) C. Everything else being the same, do you expect the air bubble to...
During a hurricane, the atmospheric pressure inside a house may blow off the roof because of the reduced pressure outside. If air (density 1.293 kg/m3) is blowing over the roof of a house at a speed of 142 km/hr, what is the pressure difference between the inside and the outside of the house?
Hydrostatic Pressure. A rectangular vertical plate is submerged in water. The top edge is horizontal and at a depth of 0.6m. The length of the vertical edge is 1.2m. determine at what dept under the water surface a horizontal line can be drawn on the plate such that the hydrostatic forces on either side of the line is equal. (Hint: The magnitude of the hydrostatic force on a vertical surface is equal to the average pressure x the area.Fluid Mechanics...
