What else can I help you with?
What most determines how hot or cold something feels when you touch it?
Heat flow determines how hot or cold something feels when you touch it.
Do heat and cold flow between objects?
Yes, heat and cold flow between objects due to the difference in temperature. Heat will flow from the hotter object to the colder object until thermal equilibrium is reached, leading to the transfer of energy.
Which is more in heat transfer between parallel and counter flow heat exchanger?
Counterflow heat exchangers typically transfer more heat to a fluid simply because the hottest part of the exchanger is where the heating medium enters the heater and the heated medium leaves the heater. In a parrallel flow exchanger the hottest part of the heater is where the heating medium enters, and the coolest part where the heated medium enters, and some temperature in between is found where both exit the heater.
Comparison of Counter-current flow and parallel flow?
Counter-current flow is more efficient then parallel flow. Shahzad, MUET Chemical Engineer
What factor most determines how hot or cold something else feels when you touch it?
The factor that most determines how hot or cold something feels when you touch it is the temperature difference between the object and your skin. Heat will transfer from the warmer object to the cooler object, resulting in a sensation of hot or cold depending on the direction of heat flow.
If a snowball was on the counter how does heat flow fron the counter to the snowball?
Yes because of the warmth in the house. That warmth will flow from the air to heat the counter top and melt the snowball
Why is the cooling water in the liebig conden ser made to run counter current to the flow of the distillate?
Running the cooling water in the Liebig condenser counter-current to the distillate flow improves the condensing efficiency by maintaining a larger temperature difference between the vapor and the cooling water throughout the length of the condenser. This allows for more effective heat transfer and a higher rate of condensation.
What are the advantages of co-current flow?
A Counter-current flow has more advantages as comapared to a co-current flow.
What direction do gyres flow in the south?
counter-clockwise
How can you describe the flow of heat?
The first statement is correct. Nature's law is that all things flow from where there is more of something to where there is less of something until they reach an equilibrium, where both sides are the same. For example, if something cold was touching something hot, then the heat from the hot object would keep flowing into the cold object until both objects are the same temperature.
Why counter corrent flow is better than cocurrent flow for heat transfer?
Counter-current flow is more efficient for heat transfer because it maintains a higher temperature gradient along the entire length of the heat exchanger, allowing for a more continuous and effective transfer of heat. As the hot and cold fluids move in opposite directions, the temperature difference between them remains large resulting in a more efficient heat exchange process. In contrast, in co-current flow, the temperatures of the fluids tend to equalize more quickly along the length of the heat exchanger, reducing the overall effectiveness of heat transfer.
What are the causes of brain freeze?
The main cause of Brain Freeze is either eating something really cold like ice-cream, or drinking something cold. The Brain Freeze is actually caused by an abrupt increase in blood flow within the brain.
