Question

2) The question is asking about the point A+B and these choices are provided: note that it is one graph but it is divided into 3 pictures. Line A+B is the first line from the right. The line A. then Line B. Which choice would it be for each? Each point is asked in three different questions with the same choices given. I need the answers For Points: a) A+B b) Point A c) Point B www ICLO 4 The A+B repet Н System curve System curve HB HB HA B A A+B Operating points Image link The flow rate of pump B if it is operating alone The flow rate of pump A if it is connected to pump B in parallel The flow rate of pump A if it is operating alone Pump A Pump B The flow rate of pump A if it is connected to pump B in series BA A+B Operating points

Answer 1

The following graph represent characterstic Carve for pump(A) and pump (B) { head developed us flow nale} syslem Curve HD le) PUMDA HA Pump B At few basic point for above curre X- operating point » The point at which system curre Griel characterslic curve intersect is known operating point of with respect to Pur77, The characterstic carre for pump and ® as operat are shown In fig.

Curve (C) is obtain by simply reddeding the head develop by pump ② and Pump (B) at each Point are ire. The carve (c) is obtain when pump and ② connected and in series in which Howrate remain same but head develop is sum of head develop by individual one. Now we are answer sway to @CA+B) Up Hand flow rate of pumpa pf it is commected to рце (2 in series." Ansor B LA oprine) "I low rate of pump (A) if it is operating alone." (B) (1 The flow rate of Pump (B) if it operating (opsion A) alone"
