Answer: The maximum velocity of fluid flowing in a circular channel occurs at the centre of the channel.
Explanation: starting from the material balance equation and going through Newton's law of viscosity.
The velocity profile of a circular channel is
V(r) = Vmax(1 - (r/R)^2))
V(r) is velocity at any point in the circular channel along the radial direction starting from r=0 at the centre and r=R at the internal side of the circular channel.
So, the maximum obtainable from that distribution is at the centre where r=0 and V(r) = Vmax.
Answer:
Kyra is more precise.
Explanation:
Kyra is more precise as she has included the exact point second it had dissolved whereas Pari just rounded it to the closest number making her write a whole number that was rounded down.
That would be a "simile."
Answer:
Technician B is correct
Explanation:
Electrical Switches makes or brakes the flow of signal (current or voltage) in a circuit.
The Technician B that says the switch contacts are closed is correct because it is until when the circuit is continues that voltage flows across the switch and voltmeter will read the amount of voltage present in the circuit. This simply means closed circuit.
Technician A is not correct because when the switch contacts are open, voltage does not flow and no reading will be measured.
