Question

About once every 30 minutes, a geyser known as Old Faceful projects water 11.0 m straight up into the air. Use g = 9.80 m/s2, and take atmospheric pressure to be 101.3 kPa. The density of water is 1000 kg/m3.

Assuming the water travels to the surface through a narrow crack that extends 5.00 m below the surface, and that the water comes from a chamber with a large cross-sectional area, what is the pressure in the chamber?

Answer 1

| Answer To determine the pressure sm below surface, which forces the waster up, apply Bernoulli's es". with point I being sm below ground, and point 2 being either at ground level or lim above ground.Let's take point o to be ilm above ground which is 16 m above the chamber where the pressurized water is. Pi=latm & fg (16) = 101.3x103+1000X9.8x16 - 101.3X10° +156,800 Pi = 258.1 kpą
