You can calculate pf very simply....you can choose EPF Calculator for that.IN that u just add your detail and monthly wage you will get all results which you needed....
Epf calculator is free you can download it from their site.
PF is 12% of your basic salary. If your basic salary is Rs. 1000/- PF will be Rs. 120 employee contribution + Rs. 120 employer contribution
If your Basic Salary is Rs. 10,000/-
12% of your Basic Salary works out to Rs. 1,200/-
3.67% of your Basic Salary works out to Rs. 367/-
8.33% of your Basic Salary comes to Rs. 833/- which is higher than the limit of Rs. 541/-
So, your Employer will contribute Rs. 541/- towards EPS and contribute Rs. 659/- towards EPF (Rs. 367/- + Rs. 292/-)
There is no rebate on PF. You only get tax benefits for PF contributions equal to the amount contributed subject to an upper limit of 1 lakh.
How do you calculate voltage drop for starting motor current
Rephrase your question so that it makes sense.
as per government go release wages in that mention basic we calculate pf on basic
kw of 100kva=100*0.8 pf=80kw( if the power factor is 0.8)
Rating for DG set and any of electrical machines is calculated in KVA. KVA is calculated as KW/pf. One can calculate the required KVA for DG set with this formulation: (KW/pf)/load rate. For example KW=110, pf=0.8 and one loads the DG at 75%, so KVA= (110/0.8)/0.75=185 KVA.
You need to fix a certain amount as basic salary if you want to deduct PF. set a minimum number as basic salary and calculate PF on it. The remaining amount based on piece rate can be added a different component in the persons salary
Since watts = volts times amps times 1.73 times power factor (for a three phase motor): W = E * I * 1.73 * PF Solving for I: I = W / (E * 1.73 * PF) Lets say your motor has a PF of 0.85: I = 10000 / (415 * 1.73 * 0.85) I = 16.39A If this is for your homework (I hope not) and PF is not given, then you will substitute 1.0 for the PF and, of course, arrive at a different answer!
KVA is the vector sum of real and reactive power; put differently, KVA at a specified power factor will tell you how many KW you have: KW = KVA * pf You must provide a power factor or power factor angle (if angle, replace pf with cos (pf) in above equation) or total reactive power to calculate.
Watts = Amps x Volts x Power Factor For a motor the Power Factor is less than 1 and might typically be about .75. For a resistive load like a toaster PF = 1. If you know the Voltage and PF and know the wattage you can calculate amps. Amps = Watts / (Volts x PF)
PF = pressure base at which volume or Btu factor is being converted from PT = pressure base at which volume or Btu factor is being converted to Mcf@PF times (PF divided by PT) = Mcf@PT 1000Mcf @ 14.73 times (14.73 divided by 14.65) = 1005Mcf @ 14.65
pf 69 is higher in value, than pf65.
