To calculate your power factor you need the following information: Watts and Volt-Amps. No other items, such as paper, books, or electronic devices are permitted in the test room. Water Treatment - Jar Testing Procedure. The formula for your power factor, also represented as Pf, is Watts divided by Volt-Amps. The t Page 17/26. Care should be taken not to damage or rip filter paper. P7. • The dosage calculation competency test is given as a proctored assessment in the college's Testing Center, located in the Library in Martin Hall. Jar test is simple device used to determine this optimum coagulant dose required. The test can be repeated by holding the pH and varying the coagulant dose. 1. Cable Calculations to the BS7671 18th edition regulations 2018. Using a 1,000 mL graduated cylinder, add 1,000 mL of raw feed water to be coagulated to each of the jar test beakers.
