WebJan 1, 2012 · Manometers can measure vacuum directly to 29.25 in.-Hg. An absolute pressure gauge shows the pressure above a theoretical perfect vacuum. It has the same U-shape as the manometer, but one leg of the absolute pressure gauge is sealed, Figure 3. Mercury fills this sealed leg when the gauge is at rest. WebNov 13, 2024 · You can measure the charge in coulombs on each by measuring the current in amps and the duration in seconds as you charge them. Then you measure the force between them in newtons and the distance between them in meters. Then ϵ 0 = 1 4 π F Q 2 r 2 The key to this is to have an independent method for measuring the charge.
WebStep 1: If your Bissell vacuum has a hose, attach the hose to the back of the vacuum. There should be a port for this. Some hoses may screw into the port, while others may click in. Step 2: Attach the accessories. Most Bissell models allow you to attach brushes, dusters, and crevice tools directly to the end of the hose.
