11. Determine pressure head, elevation head, and total head for the diagram below: 12. Use this following data to calculate the discharge of a stream: Length: 20 m , Width: 5 m , Depth: 10 m , Velocity: \( 2 \mathrm{~m} / \mathrm{s} \). Discharge \( = \) Area \( \times \) Velocity \( \quad \) Make sure your answer is in cfs (cubic feet per second)! 13. What is the porosity of a sample that contains 200 mL of sand and is completely saturated with 50 mL of water? Porosity= Volume Water/Volume Sand
