Most submarines have a distillation apparatus that can take in seawater and produce fresh water. The distillation plant heats the seawater to water vapor, which removes the salts, and then cools the water vapor into a collecting tank of fresh water. The distillation plant on some submarines can ...
The orbiter must be able to know precisely where it is in space, where other objects are and how to change orbit. To know where it is and how fast it is moving, the orbiter uses global positioning systems (GPS). To know which way it is pointing (attitude), the orbiter has several ...
An odor that's inside, duh. Ok, this is a true statement, but there's actually more to it because science, ya know. Some odors are caused by low levels of volatile organic compounds (VOCs) in the air that humans can detect. A VOC is a chemical that can turn into vapor in room t...
Damaged Canister Clogged or leaking EVAP pipes How Do You Fix The P0440 Code? To fix the P0440 code, you first want to make sure the gas cap is properly tightened, and the rubber O-ring around it seals properly. In some cases, you will need to repair a leak in the EVAP system or...
The EPA then required cars to eliminate nearly all the leaking gasoline fumes from their emissions. These EVAP systems that catch gasoline fumes are controlled largely by—you guessed it—engine vacuum. When the car is turned off, the system captures fuel vapor in a charcoal canister and then ...
windshield. Your first step should be toclean the windshieldand blades with lukewarm soapy water and then wipe with a microfiber towel soaked in rubbing alcohol. If it does not solve the issue, change the fluid. Your last resort to eliminate the streaks on the glass is to change the ...
When hibernating, groundhogs—who are never speedy—really slow down, drawing a breath only about once every five minutes. Hibernation is curious behavior: Barely breathing, these mammals cool off to just a few degrees above the ambient temperature, sometimes as low as 39º to 40ºF. Their...
These engines place the shuttle into final orbit, change the shuttle's position from one orbit to another, and slow the shuttle down for re-entry. The OMS engines burn monomethyl hydrazine fuel (CH3NHNH2) and nitrogen tetroxide oxidizer (N2O4). Interestingly, when these two substances come in...
Recessed ceiling canister lights pose special problems for a homeowner bent on making a home more energy-efficient. The older types are extremely leaky and are difficult to make airtight. Because of regulations concerning fire safety, the best you can do is to build an airtight box of flame-re...
If your pump shuts off before the tank is fuel, it’s an indicator that there’s trouble with the vapor recovery system, most often a clogged carbon canister. You’ll want to have this checked sooner than later. While You Wait for the Fuel ...
