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.

Expert Solution

Step 1

Here, we have given a problem related to the load demand required for the equipments used by a family.

So, here we know that the family is using two wall-mounted ovens having the rating of 3.5 kW

And, one counter-mounted cooking unit having the rating of 5-kW.

We know that the demand factor for any cooking equipment is 0.8.

So, first we will calculate the load demand for wall-mounted ovens and then we will calculate the load demand for

a counter-mounted cooking unit.

Then, we will add both the load demand together.

So, we will follow the below given procedure for required results.
