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.
This would be useful if you want to do calculations based on the day of the week. OPTION 2: If you'd like to return the name of the weekday, use this formula: =CHOOSE(WEEKDAY(A1),Sun,Mon,Tue,Wed,Thu,Fri,Sat). WEEKDAY(A1) will evaluate to 2, and CHOOSE will find the 2nd item in the list. OPTION 3: You can also use the TEXT function to get the name of the weekday from a date.
