Option (c) is right .we know that,
Uavg /Umax = 2 ( laminor).
Uavg /Umax =1.5(turbulent flow).
So, Umax/Uavg = 1/1.5 = 0.66.
Uavg /Umax = 2 ( laminor).
Uavg /Umax =1.5(turbulent flow).
So, Umax/Uavg = 1/1.5 = 0.66.

The ratio of maximum to average velocity in a pipe flow for;
Laminar flow is 2.
Turbulent flow 1.1 to 1.15.
So the answer is 1.
Laminar flow is 2.
Turbulent flow 1.1 to 1.15.
So the answer is 1.

Umax/Uavg = 1/.8,
=1.25.
So, the answer is 1 approximate.
=1.25.
So, the answer is 1 approximate.
