Consider two identical glasses of water, one stationary and the other moving on a horizontal plane with constant acceleration. Assuming no splashing or spilling occurs, which glass will have a higher pressure at the (a) front, (b) midpoint, and (c) back of the bottom surface?

A hot air filled balloon of 8m diameter is used to support a platform. The surrounding airis at 20° C and 1 bar while the hot air inside the balloon is at a temperature of 70° C.Determine the buoyant force and the weight that may be supported by the balloon.

A 80 cm tall cylinder is filled with water (ρwater = 1000 kg/m3) and oil (ρoil = 600 kg/m3) and is capped on the bottom so no fluid is flowing. It contains equal amounts of the two fluids by weight. What is the pressure at the bottom of the cup?

The open tank filled with a liquid in full as shown in the figure below has the height of h = 6.00 m.  The inclined angle of the inclined wall is  = 45.00 °. The width (perpendicular to the screen) of the inclined wall is w = 20.00 m. The specific weight of the liquid is  = 9.81 kN/m3. (1) For the inclined wall, determine the average pressure on it._________ (kPa)
