Re: Sentence check
A radiator is a device to cool an engine down by the process of conductoon and radiation. Typically, heated water from an engine is connected by a pipe to a radiator and goes through a coil with metal fins for heat exchange to take place. The cooled water goes out of the radiator back to the engine for cooling purposes before it is recirculated back to the radiator.
Thus the incoming and outgoing pipes connected to.the radiator cannot be the same pipe, which is why the sentence which said so was not logical to those who read it.
