Closed loop:
1. Thermostat --> furnace (constant temperature)
2. Toaster setting (light/dark) --> toast (IF the toaster has heat sensors)
3. Refrigerator cold/hot setting --> refrigerator inside temperature (constant)
4. Temperature setting for oven (not stovetop) --> oven temperature constant
5. Clothes dryer with moisture sensor
6. Washing machine water level
Furnace.
Temperature sensors control when furnace is turned on. Heating sensors in furnace control when air blower is turned on, and when flames must be turned off.
Refrigerator.
Temperature sensors control when refrigerant cycle turns on and off.
Many TV functions, internal operation of disc playback and record, really ad infinitum.

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".
What is servo drive?
A servo drive is any motor controller which uses a closed feedback loop to monitor the motors speed. This is normally accomplished through the use of an encoder or resolver.
Can a valve be installed at the end of steam expansion loop?
Yes. The expansion loop is only there to take up the thermal expansion of the pipe run, installing a valve will not impede the action of the loop.
What is hysteresis loop in stress and strain?
the leading or lagging between the stress and strain is called hysteresis loop

What are the disadvantages of closed loop systems?
its costly than open loop system and bulky, too.
Circulatory system of blue tang fish?
Fish have closed-loop circulatory systems.
Examples of the open loop system?
The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.
Why is it necessary for circuits to maintain a closed loop?
Circuits need to maintain a closed loop to allow the flow of electric current. If the loop is broken, the current cannot flow, and the circuit will not work. This is essential for the proper functioning of electrical devices and 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 is better an open-loop or closed-loop in a water craft?
The choice between an open-loop and closed-loop cooling system in a watercraft depends on the specific application and operating conditions. Open-loop systems use water from the environment for cooling and are typically simpler and lighter, making them suitable for smaller vessels. In contrast, closed-loop systems recirculate coolant, offering better temperature control and protection from contaminants, which can be beneficial for larger or high-performance crafts. Ultimately, the decision should consider factors like maintenance, environmental impact, and operational efficiency.
Closed loop gain for feedback oscillators?

Is washing machine is open loop or closed control system and why?
closed loop system
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)]
What is a flow of air in a loop?
A flow of air in a loop is commonly known as a "closed-loop air circulation system." This system involves air being circulated continuously within a defined loop or circuit to facilitate cooling, heating, or ventilation within a specific area or system without any external exposure. Closed-loop systems are often found in HVAC systems and industrial applications to maintain air quality and temperature control efficiently.
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.
