The difference between flow rate and fluid velocity along with its relation
Answer to Problem 1CQ
Flow rate is given by
Fluid velocity is given by
Explanation of Solution
Introduction: Flow rate
can also be defined as volume flow rate, it is a scalar quantity.
Fluid velocity
is a vector quantity.
Flow rate
Q is defined as volume of fluid V passes through cross section A per unit time t.
Mathematically it is given by equation,
SI unit -
CGS unit -
Fluid velocity
Mathematically it is given by equation,
SI unit -
CGS unit -
Relation between Flow rate & Fluid velocity Flow rate can be given as
Conclusion:
The greater the velocity of flow, greater the flow rate.
Flow rate is given by
Fluid velocity is given by

- Explain why the fluid reaches equal levels on either side of a manometer if both sides are open to the atmosphere, even if the tubes are of different diameters.arrow_forwardIs there a limit to the height to which an entrainment device can raise a fluid? Explain your answer.arrow_forward(a) Verify that a 19.0% decrease in laminar flow through a tube is caused by a 5.00% decrease in radius, assuming that all other factors remain constant. (b) What increase in flow is obtained from a 5.00% increase in radius, again assuming all other factors remain constant?arrow_forward

- Assuming that blood is an ideal fluid, calculate the critical flow rate at which turbulence is a certainty in the aorta. Take the diameter of the aorta to be 2.50 cm. (Turbulence will actually occur at lower average flow rates, because blood is not an ideal fluid. Furthermore, since blood flow pulses, turbulence may occur during only the high-velocity part of each heartbeat.)arrow_forwardBlood is flowing through an artery of radius 2 mm at a rate of 40 cm/s. Determine the flow rate and the volume that passes through the artery in a period of 30 s.arrow_forwardCalculate the Reynolds numbers for the flow of water through (a) a nozzle with a radius of 0.250 cm and (b) a garden hose with a radius of 0.900 cm, when the nozzle is attached to the hose. The flow rate through hose and nozzle is 0.500 us. Can the flow in either possibly be laminar?arrow_forward
