How to calculate steel pipe weight (kg/m, or lb per foot), from pipe size of diameters and wall thickness. How to check steel pipe weight chart.
Here, we have used the second formula to calculate dimensional weight – Length (cm) x Width (cm) x Height (cm) / DIM Factor – and a DIM factor of 1:6,000 to arrive at freight cost. Example 1 Freight rate: $150 per CBM/ton Package dimensions: 150 cm X 100 cm X 100 cm Gross...
Microwave-pulsing devices also can be used to "fry" the electronics of IEDs. Another device called LIBS (laser-induced breakdown spectroscopy) uses lasers to detect IED explosives within a 100-foot (30-meter) radius. Alternatively, you might not need a soldier to deal with a suspected IED ...
For example, even chargers that are switched on but not connected to devices are still using electricity. Installing a smart meter can show you information about your energy consumption and help you to see how much you’re spending, as well as sending readings directly to your supplier. By ...
Low water pressure is considered any reading that’s less than about 40 pounds of pressure per square inch (PSI). For most homes, the water pressure should be between 40 and 60 PSI, with 50 PSI being ideal. Here’s a quick, accurate way to calculate the water pressure in your home: ...
From there it enters the house through a pipe and is distributed via a system similar to that used for natural gas. Propane is billed by the gallon. Oil: Fuel oil is also transported by truck, is pumped into a storage tank either inside or outside the house, and is piped to the ...
For many years, mainland Western Europe has used a mains electricity supply rated at nominally 220VAC 50Hz while the UK used 240VAC 50Hz. In 1994, the European Union state members decided to proceed with a voltage harmonisation at 230Vac. This meant that consumers could be sure that a produc...
A volt-ohm meter (also known as a multimeter) A logic probe (optional) A regulated 5-volt power supply A collection of TTL chips to experiment with Several LEDs (light emitting diodes) to see outputs of the gates Several resistors for the LEDs Some wire (20 to 28 gauge) to hook things...
See how to use VLOOKUP to compare 2 columns in Excel to return common values (matches) and find missing data (differences).
Coulomb's law made it possible to calculate the electrostatic force between any two charged objects, but it didn't reveal the fundamental nature of those charges. What was the source of the positive and negative charges? As we'll see in the next section, scientists were able to answer tha...
