The definition for the schematic diagram.
Explanation of Solution
The diagram is one that shows the necessary significant contacts of the circuit with the flow of operation of the circuit. The schematic diagram is made by the standard symbols.
The other names for the schematic diagram is the ladder or the line diagram. The electrical schematic diagram shows the electrical sequence of the without specifying the physical location.
The schematic diagram fix the control circuit or is helpful in the troubleshooting in the control circuit.
The maintenance electrician should be aware of the schematic diagram so that the electrical can perform the maintenance or trouble shooting operation,.
Thus, the schematic diagram is explained.

- 3. A steam power plant has an average monthly net power delivery of 740 MW over the course of a year. This power delivery is accomplished by burning coal in the boiler. The coal has a heating value of 9150 Btu/lbm. The cost of the coal is $14.20/ton. The overall thermal efficiency of the plant is, nth = Wnet Qboiler = 0.26 = 26% Determine the annual cost of the coal required to deliver the given average monthly power.arrow_forward47 14 16 12 34 10 12 12 33arrow_forward= The forces F₁ = 590 lb, F₂ = 380 lb, F3 = 240 lb and F 330 lb.

- A bent pipe is attached to a wall with brackets as shown. A force of F = 180 lb is applied to the end of the tube with direction indicated by the dimensions in the figure. Determine the support reactions at the brackets B, C, and D. Model these brackets as journal bearings (only force reactions perpendicular to the axis of the tube) and neglect couple moment reactions. Assume the distance between the supports at B and C and the tube bends nearby are negligible such that the support at C is directly above the support at D and the dimension g gives the distance between supports B and C.
