4) Consider the three 1D flow setups shown below. All tubes have the same overall cross-section, and two soils of different k, with k21000 k1. 9 pts 1000 k, CASEI CASE II CASE III k, ka Figure drawn to scale- All setups extend one unit into the page Given the information provided, rank the following using 1 for the greatest, and clearly identifying any ties. NO CALCULATIONS REQUIRED - total head at point B: CASE I CASE II CASE gradient across soil 1 (soil with k-k,) CASE I CASE II CASE flow rate (q) through setup - CASE I CASE II CASE

Solution

1) total head is same for all the cases in first question.

2) In second question i = head loss per unit length , thererfore case II > case I> caseIII

3)flow rate can be calculated using formula with different k values such as in first two cases K horizontal and in 3rd case K vertical.
