There are 3 strategies to solve the turbulent flows in conduits, which are follows: goal given - find h, -L, D and Q Case 1 Case 2 goal given find Q - h, L and D - find D - Q, L and h, Case 3 goal given For cases 2 and 3, there are direct equations available as follows: For Case 2 iterative approach can be avoided sometimes by using eq as: k, 1.78v V&h, I L log 3.7D Q =-2.22D²5 Vgh, IL For Case 3 0יר 32 iterative approach can also be eliminated sometimes (L0 gh, D= ( gh, by using eg as: Select the most appropriate statement. O If hy is not available, you need to assume hf and then solve those equations for Q and D. Once you obtained Q and D, you need to check whether that Q and D are correctly assumed or not, if not you need to re-assume hf until the solution converged. O If h, is available, you can solve those equations for Q and D directly. O All the statements are correct. O For Case 1, we can get h; directly from Darch-Weishbach eq.
