![]() ![]() This effect was observed as far back as the mid-1800s, when it was found that trains passing in opposite directions tipped precariously toward one another. The reason is the same: The high velocity of the air between the car and the truck creates a region of lower pressure between the vehicles, and they are pushed together by greater pressure on the outside ( (Figure)). Similarly, when a car passes a truck on the highway, the two vehicles seem to pull toward each other. ![]() This pressure difference results in a net force, pushing the curtain inward. The reason is that the high-velocity stream of water and air creates a region of lower pressure inside the shower, whereas the pressure on the other side remains at the standard atmospheric pressure. For instance, shower curtains have a disagreeable habit of bulging into the shower stall when the shower is on. There are many common examples of pressure dropping in rapidly moving fluids. A vertical rectangular gate, 1.4m high and 2 m wide, contains water on one side. As a result, the pressure drops in a rapidly moving fluid whether or not the fluid is confined to a tube. Tutorial 3 Hydrostatic force on submerged bodies 1. Fluid Force on aVertical Surface A vertical gate in a dam has the shape of an isosceles trapezoid 8 feet across the top and 6 feet across the bottom, with a height of 5 feet. The net work done increases the fluid’s kinetic energy. ![]()
