The worst problem met in air-cooled aircraft engines was the so-called "shock cooling", when the airplane entered in a dive after climbing or level flight with throttle open, with the engine under no load while the airplane dives generating less heat, and the flow of air that cools the engine is increased, a catastrophic engine failure may ...
These systems depend on the proper operation of thermostatic air-venting valves located on radiators throughout the heated area. When the system is not in use, these valves are open to the atmosphere, and radiators and pipes contain air. When a heating cycle begins, the boiler produces steam, which expands and displaces the air in the system.
For example, if you have a 56kbs dial-up connection to the internet, you will be able to watch videos with a bit rate of 56kbs or less. (A majority of dial-up connections have speeds of 28kbs or less because of issues with the phone lines). If you try to watch a video clip with a bit rate of 300kbs over a dial-up connection, the video will not ...
