Question

Fluid originally flows through a tube at a rate of 120 cm³/s. To illustrate the sensitivity of flow rate to various factors, calculate the new flow rate (in cm³/s) for the following changes with all other factors remaining the same as in the original conditions.

(a) Pressure difference increases by a factor of 1.40.

_________ cm³/s

(b) A new fluid with 3.00 times greater viscosity is substituted.

__________ cm³/s

(c) The tube is replaced by one having 4.00 times the length.

___________ cm³/s

(d) Another tube is used with a radius 0.100 times the original.

__________ cm³/s

(e) Yet another tube is substituted with a radius 0.100 times the original and half the length, and the pressure difference is increased by a factor of 1.50.

___________ cm³/s
