Derive the relation between kwh and joule
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 ...

WebFeb 11, 2024 · The unit of energy, joule or watt-Second is too small for practical purposes, so a bigger unit mega joule (MJ) or kilowatt-hour (kWh) is used in electrical engineering. 1 kWh = 1,000 watt-hours. The kWh, also called the Board of Trade (BOT) unit, is the energy absorbed by supplying a load of 1 kW or 1,000 watts for the period of one hour. WebDerive relationship between kWh and Joule. << Previous Question Next Question >> Frequently Asked Questions Define force Write its SI unit Solution: Explanation: A physical factor that alters or tends to modify an object's state of rest or motion is called force. Newton is the SI unit of force. It is denoted by ‘N’. Final answer:
WebDerivation of the relation between (kWh) and (Joule): $1\ kWh=1\ kW\times 1\ hour$ $=1000\ Watt\times 60\times60\ seconds$ $=3.6\ 10^6\ Watt-seconds$ $=3.6\times10^6\ Joule$ Therefore, $1\ kWh$ is equal to $3.6\times10^6\ Joule$. (b). Electricity used in household $=650\ units$ WebJoules. One Joule is 1 Newton Metre, ie the work done or energy transfered to an object when a one Newton force acts on it over one metre.

WebFeb 22, 2024 · Solution, The S.I unit of energy is joules and the commercial unit of electrical energy is kWH. Now, 1 kWh = 1000 Wh Noe, we know that 1 hour = 60*60 minutes = 3600 minutes So, 1 kWh = 1000 W*3600 s 1 kWh = 3600000 Joules 1 kWh = 3.6×10₆ Joules. WebWe 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 Joule 1 s. So …
