Water at 20°C flows with a steady mean velocity of 2.0 m/s through a $100mm pipe that slopes upward at 30° to the horizontal. At point 1, the pressure is 600 kPa, and at point 2, located 25 m further along the pipe, the pressure is 460 kPa. Determine the head loss to friction, the friction factor f, and the relative roughness e/D.

Follow-up Question

Im confused wether the formula will work differently. Here is the formula for reference.

pg + 2 V₁ 2g + Z₁ = 2 P₂ V2 pg 2g +22 (4.8) Equation 4.8 is known as Bernoulli's equation. In this text we will normally use the more general equation 4.7.
