Question

At what depth of lake water is the pressure equal to 201kpa?

A. 10m

B. 20m

C. 5.1m

D. none

Answer 1

20m

Step-by-step explanation:

Pressure = pgh

p = density of water 1000

kg/m^3

g = acceleration due to gravity 9.81 m/s^2

h is the depth of water

Pressure = 201 kPa = 201 x 10^3 Pa

201 x 10^3 = 1000 x 9.81 x h

201 x 10^3 = 9810h

h = 20.49 m

Approximately 20 m
