Explanation Given data: The depth of lake is 10 m. Formula used: Write the expression for pressure at depth d in liquid ( p ) . p = p 0 + ρ g d (1) Here p 0 is pressure at the surface of liquid, ρ is density of liquid, g is gravity, which is 9.80 m s 2 . Explanation: Refer to Table 13.1 in the textbook for the densities of fluids at 1 atm pressure. From Table 13.1, the density of water is 1000 kg m 3 . The pressure on the surface of lake is as same as atmospheric pressure. Hence p 0 = 1.013 × 10 5 Pa . Substitute 1.013 × 10 5 Pa for p 0 , 1000 kg m 3 for ρ , 9.80 m s 2 for g , and 10 m for d in equation (1), p = 1.013 × 10 5 Pa + [ ( 1000 kg m 3 ) ( 9

Viscosity

The measure of the resistance of a fluid to flow is known as viscosity. Most fluids have some resistance to motion, the resistance provided by the fluid is called viscosity. This resistance is created by the force of attraction between the fluid molecule…
