Imagine that you have been employed as a consultant to design a single-jet pelton wheel that is 90% efficient with a jet velocity of vj=90 m/s. you must use a motor that runs with a torque of = 107 n. m. the jet is driven by a water reservoir at 20ºc with a head hp=325 m. now, imagine that you arrive at a design with a specific speed of ns= 0.11. determine the angular velocity (), the volumetric flow rate (q), and the radius of the wheel (r). assume ηt= 0.92 and λ = 0.5. the output torque is related to the jet velocity and the wheel radius by the expression: 2   j   qr v 

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
