water pressure of 20 cm H2O is applied at one end of tube of length 50 cm.When the other end of the tube is opened.the flow rate is 200 cm^3/min.Assuming laminar flow.calculate the flow rate if the following changes are made individually. with the other parameters set at their original values


a- the pressure were increased to 40 cm H2O

b- the length of the tube were increased to 100 cm

c- the radius of the tube were doubled

d- the water were replaced by blood, which has a viscosity approximately four times that of water
