Consider the pump and system curves indicated by the data in Table P19.72. Answer the following questions.

If the source and destination are at the same height, what is the pressure change from source to destination?

The operating condition is 1.2 L/s. What is ΔP_friction at this point?

At 1.2 L/s, what pressure change does the pump provide?

At 1.2 L/s, what is the pressure drop across the control valve following the pump?

What is the maximum flowrate possible with this (assumed single) pump?

What is the maximum flowrate possible with two identical pumps in series?

What is the maximum flowrate possible with two identical pumps in parallel?
