Final answer:
The range of differential pressures that the cell will have to respond to if the water varies between zero height above the cell measurement point and 2 m above it is from 0 to (density of water)(acceleration due to gravity)(2 m).
Step-by-step explanation:
The range of differential pressures that the cell will have to respond to if the water varies between zero height above the cell measurement point and 2 m above it can be determined using the concept of hydrostatic pressure. The hydrostatic pressure of a fluid at a certain depth is given by the equation P = ρgh, where P is the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the depth. In this case, the cell measurement point is at the bottom, so at zero height, the pressure is zero. At a height of 2 m above the cell measurement point, the pressure is given by P = ρgh = (density of water)(acceleration due to gravity)(2 m). Therefore, the range of differential pressures is from 0 to (density of water)(acceleration due to gravity)(2 m).
