31. The elevation between the two reservoirs affords a hydraulic head ( water drop ) of. 32. The drop in elevation from the intake to the turbine affords a maximum hydraulic head of. 33. The power plant contains three 10 MW Kaplan turbine-generators and has a design hydraulic head of. 34. The difference in elevation between the reservoir and power station afford a net hydraulic head of. 35. The difference in elevation between the reservoir and power station affords a net hydraulic head of. 36. The 41 MW powerhouse has a gross hydraulic head of and a maximum flow capacity of. 37. The elevation difference between the reservoir and the power station affords a net hydraulic head of. 38. The difference in elevation between the reservoir and the power station affords a net hydraulic head of. 39. This equation states that hydraulic head is a harmonic function, and has many analogs in other fields. 40. The hydraulic head can be used to determine a " hydraulic gradient " between two or more points.
