What Is The KW Formula?

What is KW equilibrium?

The equilibrium constant for this reaction is called the ion-product constant of liquid water (Kw) and is defined as Kw=[H3O+][OH−].

At 25 °C, Kw is 1.01×10−14; hence pH+pOH=pKw=14.00..

How many kW is a 200 amp service?

15-20 kWIf you have a 200 Amp service panel, use a 15-20 kW GenSet (again use the larger size if you have air conditioning or large well pump). If you have a 400 amp service panel, use a 30-50 kW GenSet (if you have lots of air conditioning or other larger loads use the large size in the range).

Is acetic acid a strong acid?

A strong acid is an acid which is completely ionized in an aqueous solution. … A weak acid is an acid that ionizes only slightly in an aqueous solution. Acetic acid (found in vinegar) is a very common weak acid because it doesn’t dissociate very much in solution Its ionization is shown below.

How many kW is 60 amps?

Is kW a KW S?

kW↔kJ/s 1 kW = 1 kJ/s. kW↔kJ/h 1 kW = 3600 kJ/h.

What is the difference between kW and MW?

One kilowatt (kW) equals 1,000 watts, and one kilowatt-hour (kWh) is one hour of using electricity at a rate of 1,000 watts. … Megawatts are used to measure the output of a power plant or the amount of electricity required by an entire city. One megawatt (MW) = 1,000 kilowatts = 1,000,000 watts.

What is the formula for KW in chemistry?

To find the pH you need first to find the hydrogen ion concentration (or hydroxonium ion concentration – it’s the same thing). Then you convert it to pH. But in pure water, the hydrogen ion (hydroxonium ion) concentration must be equal to the hydroxide ion concentration….T (°C)Kw (mol2 dm-6)pH10051.3 x 10-146.147 more rows

What is KW equal to?

One thousand WattsOne thousand Watts is one kilowatt, abbreviated kW. That’s a measure of power. If you use one kilowatt of power for an hour, you have used 1 kilowatt-hour, abbreviated kWh, of energy. One kilowatt-hour is equivalent to the energy of 1,000 joules used for 3,600 seconds or 3.6 million Joules.

Is water an acid or base?

OH – is called a hydroxyl ion and it makes things basic. However, in water, there is a balance between hydroniums and hydroxyls so they cancel each others’ charges. Pure water is neither acidic or basic; it is neutral.

How do you calculate 3ph kw?

To calculate 3 phase kWh from measuring amps on each phase Use this formula; KW= (volts(avg) x amps(avg) x power. factor x 1.732) divided by 1,000.

What is the pH formula?

Calculating_pHandpOH. To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].

How do you convert kVA to kW?

The kW to kVA Formula:Apparent power (kVA) x power factor (pf) = actual power (kW)e.g. 100 kVA x 0.8 = 80 kW.The formula for converting kW into kVA is:Actual power (kW) / power factor (pf) = apparent power (kVA)1 ton = 200 BTU/minute.1 ton = 12,000 BTU/hour.1 ton = 3.517 kilowatts.

How do you find H+ from KW?

Calculate the pH and pOH of each.1.0 X 10-3 M OH-pOH = 3.00 pH = 11.00.H+ = Kw/[OH-] = (1.0 X 10-14)/(1.0 X 10-3)= 1.0 x 10-111.0 M H+pH = 0.00 [OH-]=Kw/[H+]= 1.0×10-14/1.pOH = 14.

How many kW is a kWh?

1 kWh equals one hour of electricity usage at a rate of 1 kW, and thus the 2 kW appliance would consume 2 kWh in one hour, or 1 kWh in half an hour. The equation is simply kW x time = kWh.
