1 g mol / sec of water flows through a tube with a diameter of 2 cm. What is the velocity of the water in the tube?

water flow rate = 1 g mol / sec
= 18 g /sec
= 18 cm³/ sec

Area of tube = 3.14 X (radius)²
= 3.14 cm²

Velocity of water in a tube = (water flow rate)/ (Area of tube)
= 5.7325 cm/sec Answer
