1 Rice, the primary cereal crop grown in East Asia, is particularly suited to the warm, wet growing season. ( 2 Rice is best grown in flooded fields, or paddies.) Since rice produces a much higher yield per acre than does a crop such as wheat, it can support a much greater population per acre than does wheat.
Hydraulic Motor Circuits. These are partial circuits, illustrating some of the ways hydraulic motors can be connected. and controlled. Each circuit is condensed to its simplest form to illustrate one basic idea. These circuits can be combined with other hydraulic circuitry to make up a complete working. circuit. Parallel Motors.
Hydraulic pumps are used in hydraulic drive systems and can be hydrostatic or hydrodynamic. A hydraulic pump is a mechanical source of power that converts mechanical power into hydraulic energy (hydrostatic energy i.e. flow, pressure). It generates flow with enough power to overcome pressure induced by the load at the pump outlet.
