Data to plot a system curve and a pump curve for a pump and control valve are given below. Based on the data below, determine:

The maximum flow rate for the single pump

The maximum flow rate for two pumps in parallel

The maximum flow rate for the single pump if the pipe diameter is increased by $50\%($like going from $2^{\text{'}\text{'}}$ to $3^{\text{'}\text{'}}$ pipe$).$ explain and show all work please answer parts A to C or I will give you a thumbs down and report you also write clearly
