A 100-watt light bulb uses 100 joules of energy per second, by definition of a watt. Since there are 60 seconds in a minute and 60 minutes in an hour,…

9 watt led bulb power consumption: Yearly power consumption = 9*24*365 + 10% power loss = 78840 + 7884 = 86724 Watts hour.

The energy consumed in 1 hour will be 216,000 joules, 60 watt-hours, or 0.06 kWh.

Answer. 6000 joule energy is transferred by 100 W electric bulb in 1 minute.

Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.

100 Watts times 3600 seconds is 360,000 Joules. 0.1 kWh. E=1/2*m*V^2 → V=sqrt(2*360000/70)=101.4 m/s. 365.1 kph.

Answer Expert Verified The difference is (60 – 55) = 5 watts = 5 joules per second. (5 joule/second) x (3,600sec/hr) = 18,000 joules/hour. (5 watts) x (1 hour) = 5 watt-hours = 0.005 Kilowatt-hour.

Many light fixtures use more than one bulb and it’s easy to leave lights on throughout your house when you’re not using them. Ten light bulbs use 6 cents an hour. If you use those bulbs for 6 hours a day, it’ll cost you 36 cents a day or about $10 a month.

A kilowatt-hour is 1,000 watts used for one hour. As an example, a 100-watt light bulb operating for ten hours would use one kilowatt-hour. Below are some examples of electrical appliances found in most homes. These examples are using a 10 cents per kWh rate.

A 6,000 watt generator can power enough appliances for survival if the normal electricity supply is interrupted. It would handle a 120 volt load up to 50 amps, which should provide heat and light and keep food fresh.

Let’s use a regular 100 watt light bulb for example, lit continuously for one year (8760 hrs.), at a cost of 12 cents per KWH. 100 watts times 8760 hrs. = 876,000 divided by 1000 (converts to KWH) = 876 KWH times 12 cents = $105.12.

Based on the national average rate of 12 cents per kilowatt-hour, each hour of electric drying will cost somewhere between 24 and 72 cents, depending on the model.

Hair Dryer Electricity Costs Since it takes 1200 watts for a hair dryer to run for a full hour, that means it takes 600 watts, or 600 Wh, or 0.6 kWh to run for 30 minutes. When multiplying this usage by days in a year, at a rate of 12.19 cents per kWh, we find that you pay $26.92 per year to dry your hair everyday.

Doing coin-operated laundry will be cheaper and probably a better idea for you if…. You only do 1-2 loads of laundry a week (or less). Installing a washer/dryer in your home would require a substantial capital investment up-front.

Neglecting or mismanaging your business Bad management is the top reason why many laundromats eventually fail. All too often, a person will purchase a laundromat with the idea that as long as they collect their earnings every week or two, the business will continue running.

about 32 to 38 minutes

Our wash and fold laundry service costs just $1.25 a pound ($2.25 for same-day service).

You don’t have to tip, but I recommend it because they remember you. Definitely not required or expected but I have a soft spot for the ladies at my wash-and-fold, so I throw them a few bucks when I drop off sometimes. I tip $2 per bag, so usually $4 for my bag and wife’s bag.

With a laundry service, you get back all the time involved in the two or three washer and dryer cycles you’ll run on laundry day. Your laundry service will fold your clothes too, taking another chore off your hands. If you can’t keep up with your laundry load, a laundry service can give you back all that invested time.

To give you an idea of how much a typical load weighs, the following items all together weigh about 10 pounds: Seven pairs/sets of underwear. Seven pairs of socks. Five short-sleeve T-shirts.
