What is a sink thermodynamics?
In thermodynamics a heat sink is a heat reservoir that can absorb an arbitrary amount of heat without significantly changing temperature.
How do I measure the temperature of my sink?
1 Answer
- Given: η = 25\%
- Temp of sink = T 2 = 27 °C = 300 K.
- As η = 1 – (T 2 / T 1)
- ∴ (1/4) = 1 – [(300) / T 1]
- ∴ (3/4) = [(300) / T 1]
- ∴ T 1 = 400 K.
- i.e. Temp of source = 400 K = 127 °C.
What is the purpose of heat sink?
A heat sink is a component that increases the heat flow away from a hot device. It accomplishes this task by increasing the device’s working surface area and the amount of low-temperature fluid that moves across its enlarged surface area.
What is a sink in physics?
An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink. If the reverse is true then the object will rise – rising is the opposite of sinking.
What is a sink in engineering?
In computing, a sink, event sink or data sink is a class or function designed to receive incoming events from another object or function. The word sink has been used for both input and output in the industry.
What is efficiency of Carnot engine when temperature source and sink are equal?
Answer: The efficiency of a Carnot’s engine at a particular source and sink temperature is 12 . When the sink temperature is reduced by 100∘C, the engine efficiency, becomes 23.
What is the effect of Carnot engine when the temperature of source and sink are equal?
What is the range of the resistance thermometer?
The RTD typically can be used over a higher temperature range than a thermistor, having temperature ranges of −250 to 1000°C.
What is an example of a heat sink?
The components that generate the most heat in your computer are the CPU (central processing unit), video card (if your computer has one), and the power supply. They always have some cooling, usually a fan. Other components that may have a heat sink include the north bridge, south bridge, and memory.
What is the difference between source and sink in thermodynamics?
In thermodynamics, the source is exactly what you think it is. It is the supplier of heat. And in an ideal system, the supply is supposed to be infinite. The sink is conversely a system that can receive heat. In an ideal system, a sink can take up any amount of heat from the source. So its capacity is also supposed to be infinite.
What is a heat sink?
The sink is conversely a system that can receive heat. In an ideal system, a sink can take up any amount of heat from the source. So its capacity is also supposed to be infinite. And there is something in between the source and the sink. A working device that works with the supplied heat.
What is the fluid medium of a heat sink?
The fluid medium is usually air, but it can also be water, refrigerant, or oil. If the fluid medium is water, the heat sink is usually called a cold plate. In thermodynamics, a heat sink is a heat storage device that can absorb any heat without significantly changing the temperature.
How is heat transferred from the source to the heat sink?
Heat is transferred from the heat source. In applications that directly contact the heat sink, heat enters the heat sink through natural conduction and is removed from the heat source. The thermal conductivity of the heat sink material directly affects this process.
