Agolf course sprinkler system discharges water from a horizontal pipe at the rate of 7200 cm3/s. at one point in the pipe, where the radius is 4.00 cm, the water's absolute pressure is 2.40×105pa. at a second point in the pipe, the water passes through a constriction where the radius is 2.00 cm. what is the water’s absolute pressure as it flows through this constriction?

Explanation:

Given

Flow rate

At one Point

At second Point

Density of water

As Flow is constant therefore

Applying Bernoulli's theorem

as pipe is horizontal therefore

thus

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
