Electrical Plans

An electrical plan is also known as an electrical drawing or a wiring diagram. It is a kind of visual representation which bears the blueprint symbols of all the electrical components in electrical house plans or various building construction projects. In other words, electrical plans describe electrical circuits and systems that build up the electrical house plans or building plans. An electrical engineer who works on various construction projects creates an electrical drawing. The engineer outlines the electric planning with different symbols and lines forming a detailed electrical circuit. These drawings are a means of representation for the clients, who will carry out the actual wiring process. In a nutshell, an electrical plan showcases the circuitry with the proper placement of electric components.

A pump lifts 60°F water from a stream to a reservoir whose surface is an unknown distance above the free surface of the stream. The suction pipe (from the stream to the pump) is 250 ft of 8-in Schedule 40 steel pipe, while the discharge pipe (from the pump to the reservoir) is 2250 ft of 8-in Schedule 40 PVC (plastic) pipe. The pump consumes 150 hp and has an estimated efficiency of 85%. The suction inlet of the pump is located 2.5 ft below the surface of the stream, while the discharge port of the pump is located at the same elevation as the surface of the stream. A differential manometer connected to the suction and discharge sides of the pump measures a pressure difference of 128 psi. Consider the friction loss in the piping (using the Darcy-Weisbach equation), but neglect other (minor) losses. Flow Reservoir Pump 2.5 ft Stream
A 50-L electrical radiator containing heating oil is placed in a 50-m³ room. Both the room and the oil in the radiator are initially at 5°C. The radiator with a rating of 3 kW is now turned on. At the same time, heat is lost from the room at an average rate of 0.3 kJ/s. After some time, the average temperature is measured to be 20°C for the air in the room, and 60°C for the oil in the radiator. Taking the density and the specific heat of the oil to be 950kg/m³ and 2.2kJ/(kg °C), respectively, determine how long the heater is kept on. Assume the room is well-sealed so that there are no air leaks.

You serve as the president of XYZ corporation, which is an energy intensive manufacturing operation. You have four boilers to produce steam and electricity for your operations. One is a semi-suspension fired boiler with a capacity of 100 tons of coal per hour. The boiler can also burn supplemental fuel such as coconut or macadamia nut shells. The other three boilers arc peaking units and burn fuel oil. The City of Podunk has approached you about the possibility of burning solid waste as a supplemental fuel. As the president of the XYZ Corporation, you need to develop answers to many political, social, and technical questions before you make a commitment to the city. a. What specific questions would you ask your own power plant engineer about the possibility of accepting Podunk’s MSW? b. What specific additional data would you need from the city before you discuss this further?
