When the pumps are in parallel operation?

(a) H = H1 + H2

(b) 1/H = 1/H1 +1/ H2

(c) Q = Q1 + Q2

(d) 1/Q = 1/Q1 + 1/Q2

This question was posed to me during an online interview.

My doubt is from Selection of Pumping Units in chapter Pumps and Pumping of Environmental Engineering

Best answer
Right option is (c) Q = Q1 + Q2

Easy explanation: When the pumps are in parallel operation, then the total discharge is equal to the sum of the discharges by each pump i.e Q = Q1 + Q2.
