WebbThe Crankshaft radial piston motor has a single cam and pistons pushing inwards. Moreover, it has an extremely high starting torque and is available in single displacements from 40 cc /rev through to about 5400 cc/rev. In addition, the Crankshaft type radial piston motors can run at “creep” speeds. The hydraulic radius is one of the properties of a channel that controls water discharge. It also determines how much work the channel can do, for example, in moving sediment. All else equal, a river with a larger hydraulic radius will have a higher flow velocity, and also a larger cross sectional area through which that faster water can travel. This means the greater the hydraulic radius, the larger volume of water the channel can carry.
