Concept explainers

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.

An industrial undertaking has a connected load of 100 kW. The maximum demand is 80 kW. On an average, each machine works for 60 per cent time. Find the yearly expenditure on the electricity if the tariff is Rs 10,000 + Rs 1000 per kW of maximum demand per year + Re 1 per kWh.
Utility Electric Cost= Divide the yearly kWh by 12 to obtain the monthly kWh amount. Assume $0.20 per kWh utility cost and multiply it to obtain the amount. Use previous formulas to determine the cost ($.20/kWh) of each of these appliances of devices over a given period. 1. You take out a bagel and place it in the toaster for 5 minutes. The toaster uses 1050 watts/hour.

A small machine shop, with 30 hp of connected load, purchases electricity at the following monthly rates (assume any demand charge is included in this schedule) per hp of connected load: First 50 kWh at 12.6¢ per kWh Next 50 kWh at 10.6¢ per kWh Next 150 kWh at 9.0¢ per kWh Over 250 kWh at 7.7¢ per kWh The shop uses 2800 kWh per month. (a) Calculate the monthly bill for this shop. What are the marginal and average costs per kilowatt-hour? (b) A contract for additional business would require more operating hours per day. This will use an extra 1200 kWh per month. What is the “cost” of this additional energy? What is this per kilowatt-hour? (c) New machines would reduce the labor time required on certain operations. These will increase the connected load by 10 hp, but since they will operate only on certain special jobs, will add only 100 kWh per month. In a study to determine the economy of installing these new machines, what should be considered as the “cost” of this energy? What is…
