(a)How could you use a borometer to measure the height of a mountain pass?
(b) Why can water not be sucked to a height greater than 10 m even with a good suction pump?

(a) Air pressure decreases with height. A barometer used to measure height is called altimeter (where pressure is caliberated in terms of height).
(b) It is the atmospheric pressure [76 cm of Hg column or `(76xx13.6)cm=10.3m` of water column]
that determines the maximum height.

The power of a motor pump is 2kW. How much water per minute the pump can raise to a heiht of 10 m ? (Given g = 10 m//s^2)

A person decides to use bath tub water to generate electric power to run a 40 W bulb. The bath tub is located at a height of 10 m from the ground and it holds 200 liters of water. He installs a water driven wheel generator on the ground. At what rate should the water drain from the bath tub to light the bulb? The density of water is 1000(kg)//(m^3) and efficiency of generator is 80% . How long can he keep the bulb on if the bath tub was full initially.

The power of a motor pump is 5 kW. How much water per minute the pump an raise to height of 20 m ? Take g = 10ms ^-2 .

The maximum height of a mountain on earth is limited by the rock flowing under the enormous weight above it. Studies show that maximum height depends on young’s modulus (Y) of the rod, acceleration due to gravity (g) and the density of the rock (d). (a) Write an equation showing the dependence of maximum height (h) of mountain on Y, g and d. It is given that unit of Y is Nm^(-2) . (b) Take d = 3 xx 10^(3) kg m^(-3), Y = 1 xx 10^(10) Nm^(-2) and g = 10 ms^(-2) and assume that maximum height of a mountain on the surface of earth is limited to 10 km [height of mount Everest is nearly 8 km]. Write the formula for h.

Assertion : The power of a pump which raises 100 kg of water in 10 sec to a height of 100 m is 10 KW . Reason : The practical unit of power is horse power.
