Does anyone have an idea about how to find the coolant flow rate in the car?? Any theoretical method..
And the volume flow rate of air through the radiator?
And the volume flow rate of air through the radiator?
berko1 said:Attached is a graph that has the coolant heat flow rate divided by brake HP. I took the revs that make the most power (from dyno test) and got a value (0.95). It depends on the engine type as seen on the right corner.
Once you have the value place your engines brake Power (in KW) and compute the heat flow needed to remove (Q dot = value X power [KW]).
Now let's make a few assumptions:
The water temp entering the radiator : 100 degrees C.
The water temp exiting the radiator : 80 degrees C.
The delta= 20 C.
from the famous equation: Qdot=mDot X Cp X delta T
You can isolate the mdot and calculate it.
The graph is from an auto engineering book.. I don't remember which one.

Coolant is a liquid substance that is used to regulate the temperature of a car's engine. It is important because it prevents the engine from overheating, which can cause damage and decrease the car's performance.
Coolant flows through a series of hoses and passages within the engine, absorbing heat as it circulates. The hot coolant then travels through the radiator, where it is cooled before returning to the engine to repeat the cycle.
The flow rate of coolant can be affected by several factors, including the type and condition of the coolant, the size and design of the engine, and the efficiency of the water pump.
The flow rate of coolant can be determined by using a flow meter or by calculating the volume of coolant that flows through the system in a certain amount of time. This information can also be found in the car's manual or by consulting a mechanic.
The ideal air flow rate for a car's engine depends on its size and design, as well as the type of driving conditions. Generally, a higher air flow rate is desired for better engine performance, but too much air flow can also cause issues such as decreased fuel efficiency and engine damage.
