Pressure

Dam The wall of the dam is built thicker at the bottom to withstand a higher pressure. The generator is placed at the lower part so that the pressure of the water is high enough to drive the turbine. Submarine In deep sea, the pressure of the water is tremendously high. Hence the body of … Read more

The pressure caused by a liquid has the following characteristics: Pressure in liquid does not depends on the shape of the container. the size of the container. the area of its surface. Pressure increases with depth The deeper the liquid, the faster the liquid spurts out. In conclusion, the pressure in a liquid increases with … Read more

Usually, a U-tube is used to compare and measure the density of liquids. The density of the 2 liquids is related by the equation: h1ρ1 = h2ρ2 Example: Figure above shows a U-tube filled with water and liquid P. Liquid P is insoluble in water. Given that the density of water is 1000kg/m³, find the … Read more

Pressure in Liquids Pressure in liquid is owing to the weight of the liquid acting on the surface of any objects in the liquid. Pressure of a liquid is directly proportional to the gravitational field strength the depth density of the liquid. Pressure in liquids is not affected by the size or shape of the … Read more

The examples of application of low pressure are Foundation of Building Snow Shoes Ski Board Tyre of Tractor Feet of Elephant Strip of Handbag Seat Belt

The examples of application of high pressure are: Sharp Knife Ice-Skate Sole of shoes with spike

In SPM, you need to know The definition of pressure The formula of pressure (you need this formula to do lot of calculation.) The SI unit of pressure Factors affecting the magnitude of pressure Pressure Pressure is defined as the force acting normally per unit area. (Here, the word “normally” means perpendicularly.) Example As shown … Read more
