What advantages has closed loop hydraulic systems over open loop hydraulic systems?

A closed loop system does not permit the escape or waste of the working fluid.
open system:
A bucket of water with a hole in the bottom that allows a stream of water to fall upon the blades of a turbine and spin it, performing work, can be considered an open system because the water, the working fluid, is not captured and recirculated for re-use but allowed to fall on the ground and drain away.
(I have ignored possible return methods such as the earth's weather system, city storm drains, wells and manpower, and the water utility for this example)
A better example might be that of a jet aircraft engine. The fuel is burned to create hot pressurized gas, which is the working fluid. The working fluid expands through the engine's turbine, turning it and producing work. The working fluid is not recovered, but thrown away into the air.
closed system:
The hydraulic system that lifts the bed of a dump truck and the Power Steering system in a car are both closed systems because in each one the working fluid is returned to a closed tank for re-use after it has been used to perform work.

What is closed loop hydraulic systems?
It means that the pressurising medium does not leave the system and it is recirculated with make-up or top-up quantity as and when required. This makes it a sealed system to work with.
What are the disadvantages of closed loop systems?
its costly than open loop system and bulky, too.
What is the definition of closed loop control system?
A closed loop control system is a set of mechanical or electronic devices that automatically regulates a process variable to a desired state or set point without human interaction. Closed loop control systems contrast with open loop control systems, which require manual input.
What is an open loop system?
Open Loop control Systems have input, then the input is processed by various components like amplifiers, filters etc, then final out stage.The main difference between open loop and closed loop systems is that in open loop systems there is no feedback.
Is a lawyer a open or closed loop?
It depends. Which is more corrupt? -- An open loop or a closed loop? Whichever one is more corrupt, selfish, and greedy, then that is the one that befits attorneys.

What are the advantages of closed loop control system?
stability and repeatability

What is the difference between a hydrostatic and a hydraulic system?
By "Hydrostatic" systems one tends to mean "closed loop hydraulic systems". That is hydraulic systems comprising a pump and motor hwere the pump supplies the motor whose return side supplies the pump. The speed and direction of rotation of the hydraulic motor being changed according to the displacement angle of the variable displacement axial pison pump. "Open loop hydraulic systems" on the other hand comprises various motors often one or more "linear motors" (hydraulic cylinders). When using hydraulic cylinders in hydraulic systems one needs a reservoir to be able to hold the various volume need of the cylinder. (the displacement on the piston side is usually bigger than the rodside). The reservoir needs a "breather" due to the varous displacement needs hence the "open system".

Circulatory system of blue tang fish?
Fish have closed-loop circulatory systems.
What is a closed loop system?
A control system that appears to be self-regulating. Closed-loop systems employ feedback and a reference of correctness (norm or set point). Deviations from the norm are detected and corrections made in order to maintain a desired state in the system. Closed loop systems provide the homeostatic mechanism of many physiological functions (see negative-feedback) and also control some movement patterns, where feedback from proprioceptors and other receptors play an important part. Compare open-loop-system.
What are the examples for open and closed loop control systems with their block diagrams?
traffic signal,blind person,

What is the difference between finite open loop gain and closed loop gain?
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
