Derive the relation of 1 kwh with joule
WebSolution We can establish a relation between kilowatt-hour (kWh) and Joule (J) as – 1 kilowatt-hour = 1 kilowatt for 1 hour = 1000 watt for 1 hour But, watt Joule s 1 watt = 1 … WebOne joule is equal to 2.777778⋅10 -7 kilowatt-hours: 1J = 2.777778⋅10 -7 kWh = (1/3600000)kWh So the energy in kilowatt-hour E(kWh) is equal to the energy in joules …

Web(a). Derivation of the relation between (kWh) and (Joule): 1 k W h = 1 k W × 1 h o u r = 1000 W a t t × 60 × 60 s e c o n d s = 3.6 10 6 W a t t − s e c o n d s = 3.6 × 10 6 J o u l e Therefore, 1 k W h is equal to 3.6 × 10 6 J o u l e. (b). Electricity used in household = 650 u n i t s = 650 k W h [commercial unit of power is k W h] WebA joule is a unit of energy equivalent to a “ watt - second ”. A Kilowatt-hour is therefore 1000 × 3600 joules. ( Kilo = 1000, and 3600 seconds per hour ). Step 2: Finding the relation …
WebOne joule is equal to 2.777778⋅10 -7 kilowatt-hours: 1J = 2.777778⋅10 -7 kWh = (1/3600000)kWh So the energy in kilowatt-hour E(kWh) is equal to the energy in joules E(J) divided by 3600000: E(kWh) = E(J) / 3600000 = E(J) ⋅ 2.777778⋅10 -7 Joules to kWh conversion table kWh to Joules conversion See also kWh Joules to kJ conversion WebOne kilowatt-hour is the amount of energy delivered by the flow of l kilowatt of electricity for one hour. Use conversion factors to show how many joules of energy you get when you buy 1 kilowatt-hour of electricity. See Answer 6. An escalator is used to move 20 passengers every minute from the first floor of a department store to the second.
WebA kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a non-SI unit of energy: one kilowatt of power for one hour. It is equivalent to 3.6 megajoules (MJ) in SI units.

WebThat is, we want to derive the Joule-Thomson coefficient, µ = (∂ T /∂ P) H. Now entropy is a function of state – i.e. of the intensive state variables P, V and T. ( V = molar volume.) But the intensive state variables for a particular substance are related by an equation of state, so we need express the entropy as a function of only two ...
