Thus, assuming the turbine to be tested to be of 3000 kilowatt capacity normal load, with a guaranteed steam consumption of, say, 14.5 pounds per kilowatt-hour, he calculates the total water rate per hour, which in this case would be 43,500 pounds, and designs his weighing or measuring tanks to cope with that amount, allowing, of course, a marginal tank volume for overload requirements.
Merely subtract the previous reading from the last one, which will give 45, or the number of kilowatt-hours from which the bill for electricity is computed. If electricity costs 3 cents a kilowatt-hour, which is the price charged in some localities, the bill should come to 45 X .03 or $1.35. Before stoves for cooking came into use in the home, food was cooked in open fireplaces.
Here again rules exist, one of these being that every additional inch of vacuum increases the economy of the turbine by something slightly under half a pound of steam per kilowatt-hour. But a moment's consideration convinces one of the utter unreliability of such rules for general application.
Knowing the general nature of the power and confident that Dick would control it, I have already drawn up sketches for a power-plant installation of five hundred thousand electrical horsepower, which will enable us to sell power for less than one-tenth of a cent per kilowatt-hour and still return twenty percent annual dividends. However, the power-plant comes after the flyer." "Why?
Twelve o'clock came and went, and one o'clock and two o'clock. Still the slow crystallization went on. Buck Kendall was casting furtive glances at the kilowatt-hour meter. It stood at a figure that represented twenty-seven thousand dollars' worth of power. Long since the power rate had been increased to the maximum available, as the power plant's normal load reduced as the morning hours came.
Since 1,000 hours equal 1 kilowatt, 1,000 watt-hours equal 1 kilowatt-hour.
