Answer the following statement(s) true (T) or false (F)
1. The system head loss curve that describes head loss versus flow rate in a specific piping system is not very dependent on fluid properties and temperature. 2. Circulators with “flat” pump curves should be used when the objective is to maintain a relatively steady pressure differential across the distribution system over a wide range of flow rates. 3. When two identical circulators are connected in series, the resulting pump curve can be found by doubling the head produced by a single circulator at each flow rate. 4. The pump curve for two identical circulators connected in parallel is obtained by doubling the flow rate of a single circulator at each head value. 5. For a liquid at a given temperature, cavitation occurs anywhere the liquid’s pressure drops below its vapor pressure.
