A hydraulic engineer is studying the pressure in a particular fluid. The pressure is equal to the atmospheric pressure 101 kN/m plus 8 kN/m for every meter below the surface, where kN/m is kilonewtons per meter, a unit of pressure. CAREERS IN MATH a. Write an expression for the pressure at a depth of d1 meters below the liquid surface. b. Write and solve an equation to find the depth at which the pressure

Step-by-step explanation:
The pressure is equal to the atmospheric pressure 101 kN/m plus 8 kN/m for every meter below the surface, therefore;
a. expression for pressure is given by,
............................... (1)
where d = depth below the surface in meter.
b. to find the depth at any pressure, equation (1) above is rearranged to make depth (d) subject of the formula
as an example, to find depth at pressure of 200N/m
d = (200 - 101)/8 = 12.375 meters
depth is 12.375 meters below the surface.
