Plumbing is the system of pipes, drains, fittings, valves, and fixtures installed for the distribution of water for heating, washing, and sanitation.

• Plumbing involves the installation and maintenance of pipes, drains, and fixtures for water distribution.

• It includes systems for heating, cooling, and sanitation in buildings.

• Plumbers use various tools and materials such as pipes, fittings, valves, and wrenches.

• Common plum...read more

Various tools are used in plumbing such as pipe wrenches, pliers, pipe cutters, and plungers.

• Pipe wrenches are used to tighten and loosen pipes and fittings

• Pliers are used for gripping and turning nuts and bolts

• Pipe cutters are used to cut pipes to the desired length

• Plungers are used to clear clogged drains

The refrigeration cycle is a process in which a refrigerant absorbs heat from a low-temperature area and releases it in a high-temperature area.

• The refrigeration cycle starts with the refrigerant entering the compressor as a low-pressure gas.

• The compressor then compresses the refrigerant, raising its temperature and pressure.

• The high-pressure, high-temperature refrigerant gas then flows into the condenser where it rele...read more

A chiller plant typically goes through multiple cycles to cool a building or facility.

• A chiller plant usually has multiple cycles throughout the day to maintain the desired temperature in a building.

• The number of cycles can vary depending on factors such as the size of the building, weather conditions, and cooling load.

• For example, a chiller plant in a large office building may go through several cycles during peak hou...read more

Chiller approach can be calculated by subtracting the chilled water supply temperature from the leaving chilled water temperature.

• Calculate the difference between the leaving chilled water temperature and the chilled water supply temperature.

• Approach = Leaving Chilled Water Temperature - Chilled Water Supply Temperature

• A typical approach value is around 3-5 degrees Fahrenheit.

• Approach is an important parameter to monit

Maintaining power factor involves reducing reactive power consumption and improving power factor correction.

• Install power factor correction capacitors to offset reactive power

• Regularly monitor power factor and adjust capacitor banks as needed

• Reduce harmonic distortion to improve power factor

• Use energy-efficient equipment to reduce reactive power consumption

Ohm's law states that the current flowing through a conductor is directly proportional to the voltage across it, and inversely proportional to the resistance of the conductor.

• Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current, voltage, or resistance in a circuit when the other two values are known.

• For example, if a circuit has a v...read more
