Attach a micron gauge to the male flare end, a gauge to the tee end, and a line from the tee to the pump. Turn the pump on and you will notice the side closest to the pump will be a lot lower than the other.
The WEEKNUM function is used in Excel to return the week number of a specific date in the year (a number between 1 and 54). It has two arguments, the 1st is required and the 2nd is optional: WEEKNUM(serial_number, [return_type]) Serial_number - any date within the week whose number you are trying to find.
For example, if you want to display days of week as the first 2 letters, enter them as value arguments in the CHOOSE function: =CHOOSE(WEEKDAY(A2),Su,Mo,Tu,We,Th,Fr,Sa). In this formula, the Excel WEEKDAY function gets the day of week as a serial number.
