True or False? The higher the velocity of the fluid the lower the pressure.

The water pressure acting on a submarine at depth is 2.6 x 106 Pa.  What is the magnitude of the force (in kN) that acts on a hatch door with an area of 0.87 m2

help A piece of wood floats in water. It measures 49 cm x 12 cm x 11 cm, and has a density of 500 kg/m3. Find the percent of the wood that's underwater, if the density of water is 1000 kg/m3 Hint: Answer should be between 0 and 100 % Buoyancy problem: draw the wood and the forces on it - namely gravity pulling down and the buoyant force of the water pushing up ∑F = 0 the buoyant force = Fb = density of fluid x g x Volume underwater = density of fluid x g x percent * total volume  solve for percent

A fluid passes through the tube with a mass flow rate of 1.50 kg/s. If the tube's diameter narrows to half its original diameter, then its mass flow rate will be, 0.375 kg/s 0.75 kg/s 1.06 kg/s 1.50 kg/s 2.12 kg/s 3.0 kg/s 6.0 kg/s
