The rate at which charges move through a conductor is called?
there is no name for the rate of charge transfer, but its inverse is resistance: resistance is how much charge is resisted, so a low resistance material will have a larger rate of change of charge than a high resistance material.
What is thermal risistance?
Thermal resistance is a measure of a material's ability to resist the flow of heat through it. It is used to quantify how well a material can insulate against heat transfer. A lower thermal resistance value indicates better thermal insulation properties.
What is resistance power?
All resistances will emit heat energy when a current flows. The heat production rate (or power) can be found by any of these formulas: Power = Current * Voltage Power = Current2 * Resistance Power = Voltage2 / Resistance. Power is given in Watts when Current is in Amps, Voltage in Volts, and Resistance in Ohms.
How does heat transfer from a rock to an animal?
Heat transfers from a rock to an animal through conduction. When the animal comes in contact with the rock, the heat energy from the rock moves to the animal through direct contact. The rate of heat transfer depends on factors like the temperature difference between the rock and the animal, the thermal conductivity of the rock, and the duration of contact.
How is resistance used in a space heater?
In an electrical space heater, electrical current dissipates energy into heat, and the heat radiates from the element. In a fuel powered space heater, an orifice throttles the fuel feed (resistance to flow), which controls the heating rate. In a steam powered space heater, an orifice throttles the steam (resistance to flow), which controls the heating rate.
Low-speed filling?
Heat conduction controls Low shear rates, high local viscosities, and high flow resistance at low filling rates.Due to the slow replenishment rate and slow flow of hot plastic, the heat conduction effect is more obvious, and the heat is quickly taken away by the cold injection mold wall.Coupled with a small amount of viscous heating, the thickness of the solidified layer is thicker, which further increases the flow resistance at the thinner wall.
What is thermal admittance?
This is the rate of flow of heat between the internal surfaces of the structure and the environmental temperature in the space, for each degree of deviation of that temperature about its mean value.
What is the difference between Drop wise condensation and film wise condensation?
heat transfer rate high
Does an object on the moon move faster or on earth?
Through its atmosphere? Yes because there are no molecules of nitrogen, oxygen etc in gas form to provide resistance which is why any vehicle entering earths atmosphere at a high rate of speed will burn up if it doesn't have some type of heat shield or heat tiles to dissipate the heat caused by the friction of the object colliding with gas particles.
How does dirty overall heat transfer coefficient affect water flow rate?
A decrease in the overall heat transfer coefficient due to fouling or dirt buildup can reduce the efficiency of heat transfer in a system. This can lead to a decrease in the water flow rate as the system needs to compensate for the reduced heat transfer efficiency. Increased resistance to heat transfer can result in higher energy consumption and reduced performance of the system.
How At high temperatures the rate of enzyme action decreases because the increased heat?
alters the active site of the enzyme
How efficient is the respiratory system of a yak?
The respiratory rate of a yak increases with heat and at low altitudes, while at higher, cooler climates, the rate decreases. This helps the animal adjust to the varying climates.
