1.6. Different Pipe Inlets

Try these first

1. 1.

   What is the formula for calculating head loss due to sudden enlargement?

   Hint

   Remember K_L is a loss coefficient.

2. 2.

   Define entrance loss in pipe systems.

   Hint

   Think about how fluid enters a wider area.

3. 3.

   What is the primary factor causing head loss in sudden enlargement?

   • Fluid density
   • Loss coefficient
   • Pipe length

   Hint

   Focus on energy transitions.

4. 4.

   Is the loss coefficient $K_E$ typically greater than 1 for pipe exits?

   • True
   • False

   Hint

   Think about energy loss at exits.

5. 5.

   You have a 30 mm pipe that enlarges to 90 mm. Calculate the head loss for a fluid exiting at 2 m/s. Assume clean conditions and derive K_L.

   Hint

   Use the K_L formula to derive, then apply the head loss formula.

6. 6.

   A reservoir feeds a pipe entrance with a coefficient of 0.3. If the fluid velocity is 1.5 m/s, calculate the entrance loss.

   Hint

   Use entrance loss calculation, considering velocity.
