1. Question 1

   Q1. Water flows through a pipe of radius 0.02 m at a velocity of 3 m/s. What is the volume flow rate?

   • A) 3.77 x 10^-3 m³/s
   • B) 3.77 x 10^-4 m³/s
   • C) 1.88 x 10^-3 m³/s
   • D) 1.88 x 10^-4 m³/s

   Answer: 3.77 x 10^-3 m³/s

   Explanation: Volume flow rate = Av = πr²v = π(0.02)²(3) = 3.77 x 10^-3 m³/s; correct calculation.
