Answer:

The volumetric flow rate is 0.00589 cm³ /s

Step-by-step explanation:

Given;

length of the tube, L = 200 mm = 20 cm

diameter of the tube, 1.5 mm

radius of the tube, r = 0.75 mm = 0.075 cm

Area of the tube is given by;

A = πr²

A = π(0.075)² = 0.0177 cm²

Velocity of water through the tube is given is by;

v = L / t

v = 20 cm / 60 s

v = 0.333 cm / s

Volumetric flow rate of water is given by;

Q = Av

Q = (0.0177 cm²)(0.333 cm / s)

Q = 0.00589 cm³ /s

Therefore, the volumetric flow rate is 0.00589 cm³ /s
