Explanation / Answer

1. 7.5

2. Pump (This boosts the pressure by converting electrical energy into mechanical energy.)

3. Copper (Copper pipe, or 'tube', is commonly joined by soldering. When applied in a plumbing trade context in the United States, soldering is often referred to as sweating, and a tubing connection so made is referred to as a sweated joint , Reference: Wikipedia)

4.Mutual Inductance.

5. Sewage Ejector Pump

6. Cold Air

7. Dry Pipe System (Dry pipe systems are most often used in unheated buildings)

8. Pre Action System ( This is a hybrid of Dry pipe system and wet pipe systems. Since dry pipe systems which can be operated with timedelay are involved in this kind of system, this kind of system provide time delay.)

9. Control Point (Offset is the Difference between the measured controlled variable and the setpoint)

10. Supply/ return diffuser air flow maximum capacity.
