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 systems are used to control and transmit power. A pump driven by a prime mover such as an. electric motor creates a flow of fluid, in which the pressure, direction and rate of flow are controlled by. valves. An actuator is used to convert the energy of fluid back into the mechanical power. The amount of. output power developed depends upon the flow rate, the pressure drop across the actuator and its overall. efficiency. Thus, hydraulic actuators are devices used to convert pressure energy of the fluid into. mechanical energy. Depending on the type of actuation, hydraulic actuators are classified as follows: 1. Linear actuator: For linear actuation (hydraulic cylinders). 2. Rotary actuator: For rotary actuation (hydraulic motor). 3.
