A viscous fluid is flowing through a small tube at a rate of 0.200 m3/s. If the pressure difference across the tube is doubled, and the length of the tube is halved, and the radius is also doubled, then what is the new rate of flow of the fluid?

The flow rate of a liquid is _______.Question 7Select one:A.directly proportional to the pressure gradient and the resistanceB.directly proportional to the pressure gradientC.directly proportional to the resistanceD.inversely proportional to the pressure gradient

Poiseuille's Law describes flow rate through a cylinder. Which of the following statments is correct?Question 5Select one:a.Poiseuille's Law applies to laminar flow.b.Poiseuille's Law only applies in the absence of friction.c.Poiseuille's Law applies to a tube with varying radius.d.The flow rate is proportional to the length of the tube.e.The liquid flows due to its weight, and the effect of the flow is to cause a pressure difference between the ends of the tube.

The radius of a right circular cylinder increases at the rate of 0.2 cm/sec and the height decreases at the rate of 0.1 cm/sec. The rate of change of the volume of the cylinder when the radius is 1cm and the height is 2cm is
