Question

A meat baster consists of a squeeze bulb attached to a plastic tube. When the bulb is squeezed and released, with the open end of the tube under the surface of the basting sauce, the sauce rises in the tube to a distance h, as the drawing shows. Using 1.013 × 105 Pa for the atmospheric pressure and 1300 kg/m3 for the density of the sauce, find the absolute pressure PB in the bulb when the distance h is (a) 0.19 m and (b) 0.08 m.

Explanation / Answer

a) Pbulb + p g h = Patm

Pbulb = (1.013 * 105) - (1300 * 9.8 * 0.19)

= 9.88 * 104 Pa

b) Pbulb + p g h = Patm

Pbulb = (1.013 * 105) - (1300 * 9.8 * 0.08)

= 10.0 * 104 Pa
