Why do old people’s legs swell up?

How to calculate compression ratio?
Calculating compression ratio is pretty straightforward, but involves a little math. So, grab your calculator and let’s crunch some numbers. Compression Ratio is the total volume of the engine divided by the clearance volume of the engine.
Can melolin be used to treat leg ulcers?
In common with other perforated plastic film dressings, Melolin should be used with caution in the treatment of leg ulcers that produce copious quantities of very viscous exudate. Under these circumstances, the exudate may become trapped under the dressing, leading to maceration and inflammation of the surrounding skin.
What is the compression ratio of a diesel engine?
Diesel engine. The appropriate compression ratio depends on the design of the cylinder head. The figure is usually between 14:1 and 23:1 for direct injection engines, and between 18:1 and 23:1 for indirect injection .
What are the disadvantages of higher compression ratio?
Higher compression ratios can make gasoline (petrol) engines subject to engine knocking (also known as “detonation”, “pre-ignition” or “pinging”) if lower octane-rated fuel is used. This can reduce efficiency or damage the engine if knock sensors are not present to modify the ignition timing.
