Question

Measured along the surface of the water, a rectangular swimming pool has a length of 15.1m. Along this length, the flat bottom of the pool slopes downward at an angle of 12.3degrees below the horizontal, from one end to the other. By how much does the pressure at the bottom of the deep end exceed the pressure at the bottom of the shallow end?

Measured along the surface of the water, a rectangular swimming pool has a length of 15.1m. Along this length, the flat bottom of the pool slopes downward at an angle of 12.3 degree s below the horizontal, from one end to the other. By how much does the pressure at the bottom of the deep end exceed the pressure at the bottom of the shallow end?

Explanation / Answer

difference betwee depth of shallow end and deep end = L * tan theeta = 15.1 * tan 12.3 = 3.29233 m

so.. difference in pressure = 1000 * 9.8 * 3.29233 = 32264.8578 Pa
