If the pressure rise ΔP across a pump is half the discharge pressure, then which of the following relates the suction pressure Ps to discharge pressure pd?

If the pressure rise ΔP across a pump is half the discharge pressure, then which of the following relates the suction pressure Ps to discharge pressure pd? Correct Answer 2 x Ps = Pd

pd = Ps +ΔP. Since ΔP = 1/2 Pd, Pd = 2Ps.

Consider the following statements and choose the correct answer:
1. A direct proportionality exists between vapour pressure and the concentration of water vapour in the atmosphere
2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity
