Question

Refer to Q7, 8, 9 and 10, and determine the motor Power required using estimated losses at 30%.

(a) 5.3 Hp

(b) 6.3 Hp

(c) 5.6 Hp

(d) 6.6 Hp

I had been asked this question in an internship interview.

My doubt stems from Power Requirements for Mixing topic in section Fluid Flow and Mixing of Bioprocess Engineering

Answer 1

The correct option is (d) 6.6 Hp

Best explanation: PMotor = PDelivered / ( 1 – Losses )

PMotor = 5.3 / ( 1 – 0.20 )

PMotor = 6.6 Hp.
