31. The penstocks for generators one through four had a diameter and were in length. 32. Each of these four penstocks will supply water to the turbines during power generation. 33. Water from the reservoirs is sent to the power station via a long penstock . 34. Water from the reservoirs is sent to three separate power stations via of penstock . 35. Water flows to the power plant from the dam through the penstock with diameter. 36. The two reservoirs are connected through underground penstocks . 37. The conduit bringing high-pressure water to the impulse wheel is called the penstock . 38. Consequently, the dam, penstocks and other works associated with it remain in use. 39. Penstocks for hydroelectric installations are normally equipped with a gate system and a surge tank.40. Much investigation went into the accident resulting in the almost complete redesign of the penstock .
