Pf formula. I was planning toprepare the formula format for pf but you made my work easy. Example present value of a future payment. P present value.
Pao2 fio2 p represents pao 2 arterial po2 from the abg. P divided by f pf ratio. The power factor can get values in the range from 0 to 1.
This representation comes from the algebraic equivalence pfpf. P f 1 i n 2 where. When all the power is reactive power with no real power usually inductive load the power factor is 0.
An payment of 5000 is received after 7 years. 90 040 pf ratio 225. How to calculate the pf ratio.
The pf ratio 90 divided by 40 225. It helped me a lot. Thanks usha 11th july 2008 from india hyderabad.
The discount rate can be calculated. To convert f to p multiply f by the discount factor pfin. N number of periods.
23rd december 2008 from india calcutta. The braces around the excel formula indicate that the formula must be entered as an array function using ctrlshiftenter. Please give a revised excel calculation sheet for pf with salary more than rs6500 per month.
Calculate the present worth or value of this payment with dicount rate 5. Suppose the po2 is 90mmhg on 40 oxygen f io2 40. F single future payment.
In ac circuits the power factor is the ratio of the real power that is used to do work and the apparent power that is supplied to the circuit. Pao 2 90 on 40 oxygen fio 2 040. The po2 on room air in this case would have been about 45 mmhg well below the cut off of 60mmhg.
