Question
SAE 30W oil at 20°C flows through a straight pipe 25 m long, with diameter 4 cm. The average velocity is 2 m/s.(a) Is the flow laminar? Calculate (b) the
pressure drop and(c) the power required. (d) If the pipe diameter is doubled,for the same average velocity, by what percent does the required power increase?
