1. Tractive work – 2. Stationary work – requiring pulling or usually accomplished by drawing efforts. means of a belt, gears, PTO, direct drive, electric Ex. Plowing or land motors. preparation, planting and seeding, crop cultivation, Ex. Water pumping, harvesting, and hauling. processing, silage cutting, etc Savonius Power, (kW) = (Q * H)/102 where: Q = mass flow rate, kg/s = ρ VA ρ = density of water, kg/m3 V = velocity, m/s A = Area, m2 H = head or vertical drop of water, m The actual power of water wheels is 60 to 80% of the theoretical due to the following: Hydraulic losses in conduit and turbines Mechanical losses in bearings and power transmission systems Electrical losses in generators, station use and transmission (hydro-electric) ⚬ ⚬ Power generation using steam turbine or steam engine. Source of heat in food and feed processing operations. Grain drying
