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.
A hydraulic drive is a device that uses pressurised fluid in order to drive the machinery and it is made up of many components, of which an important one is the hydraulic pump which can have a power density of up to 10 times that of an electric motor.
