Learn how plumbing functions as a system of pipes and fittings that carries water and other fluids, including potable water, waste removal, and heating, cooling, and gas transport.

The video presents the two main objectives of building plumbing—providing water for human use and removing wastewater—covering distribution pipes, fixtures, and building and storm drains.

Explore the water distribution system, from collection, transmission, and treatment to storage and distribution, delivering water from source to homes, businesses, and industries via gravity and pumps.

Learn about the four major types of water distribution systems and their use in various societies, commercial areas, and irrigation.

Describe tree distribution systems where water from a central main pipe splits into branches to supply houses, with layouts including perpendicular, circular, and irregular patterns.

Learn about radial distribution system and circular distribution system for water supply, delivering water from reservoirs through branches to consumers in all directions.

Explore the two main types of water distribution systems, focusing on the water supply system that delivers potable water from a source to every floor and fixture in a building.

Define plumbing fixtures as exchangeable devices connected to the plumbing system that deliver water and drain it, with examples including kitchen and closet fixtures.

Explain minimum flow rate and pressure for common plumbing fixtures, including bathtubs, showers, water closets, urinals, dishwashers, and sinks, and how these determine required pipe sizes.

Explore how water storage works, including overhead and underground tanks, and compare RCC, plastic, fiberglass, and galvanized steel tanks used for durable water storage in homes, agriculture, and other applications.

Compute daily per-person water consumption with practical allocations for drinking, cooking, lighting, flushing, washing clothes, dental care, and gardening, totaling about 135 liters per person per day as an average.

This excel sheet calculates daily water consumption for residential, office, factory, and hotel buildings by inputting occupants or rooms, using per-person rates like residential 135 litres and office 60 litres.

Estimate household water demand from the number of people, convert to cubic feet using 28.7 liters per cubic foot, and compute tank size from height and tank shape formulas.

Calculate water demand for 160 people at 135 to 21,600 liters; add 15% contingency and 15% safety to 900 cu ft, 150 sq ft with 15 by 10 ft.

Explore piping as a system moving fluids such as water, diesel, petrol, and natural gas. Learn piping materials, design, stress analysis, and codes (ASME, ASTM, API, ANSI).

Learn about copper pipe for hot and cold water supply, highlighting corrosion resistance, light weight, ease of installation, lower cost than steel, recyclability, and potential acidity-related limitations.

Explore galvanized steel pipes used in water, sewerage, and firefighting systems, noting heavy handling, zinc coating risks, potential internal rusting, reduced water pressure, clogging, and lead release concerns.

Explore polyvinyl chloride pipe, its rigid, corrosion-resistant properties, and advantages for home water supply lines, including low cost and easy installation, along with hot-water and hard-water limitations.

Learn about CPVC pipe, a chlorinated polyvinyl chloride system for high temperature plastic pressure piping, offering flexibility, corrosion resistance, and safe hot and cold water delivery.

Explore HDPE pipes and how their properties depend on manufacturing processes like blow molding, injection molding, and extrusion, with applications in gas, fuel, chemical, and water systems.

Explore valve functions to start, stop, and direct fluid flow, relieve pressure, and review gate valve and globe valve types, their advantages and drawbacks.

Explore check valves, allowing flow in one direction and preventing backflow in pumps and compressors, using pressure and springs to open or close, reducing water hammer and equipment damage.

Explore the butterfly valve design and operation, highlighting quick open/close action and compact use in small spaces, along with limitations for one-direction flow, high pressure, and chemical flow.

Explore how a globe valve regulates flow in a pipeline, with a movable plug that raises and lowers to stop or allow fluid, and its key components.

Increase the energy of liquids and move them from low to high pressure with a pump driven by a motor and impeller.

Explore the two main pump types—dynamic and positive displacement—and how their energy is added: through rotating blades for dynamic pumps and fixed-volume trapping for positive displacement pumps.

Explore centrifugal pumps as a rotary pump where the impeller and shaft convert electrical energy into mechanical energy and fluid energy, transforming kinetic energy into potential energy to raise pressure.

Explore centrifugal pump components, including the motor, impeller, stuffing box, packing, shaft, casing, and discharge nozzle after the impeller. Relate these parts to plumbing and fire protection system design.

Explore multi-stage centrifugal pumps with multiple impellers inside a single unit to achieve higher discharge pressure. Learn how these configurations enable efficient pumping of water or fluids at elevated pressures.

Explore centrifugal pumps and priming, showing why submerging the impeller in liquid is essential for suction and energy transfer, and why starting after priming matters.

Explore pump types, from radial pumps with pistons that transfer energy to water, to flow and mixed-flow pumps delivering high pressure, high discharge, and low-noise, reliable operation.

Explore how various pump types—gear pumps (external and internal), screw pumps, lobe pumps, and reciprocating pumps—convert electrical energy to fluid energy, delivering high-pressure discharge with differing efficiencies and limitations.

Learn to calculate pump horsepower from flow rate, total dynamic head, and friction losses, then adjust for specific gravity and pump efficiency to determine required water horsepower.

Apply the water supply fixture units table to determine minimum branch sizes and total gpm for a building, sizing cold and hot water pipes across dwelling units.

Calculate minor losses in plumbing and fire protection systems by summing loss coefficients for elbows, reducers, and inlet/outlet fittings, then multiply by velocity head to obtain total head loss.

Major losses are friction losses from fluid moving through a pipe, caused by wall contact. They depend on diameter, velocity, absolute roughness over diameter, and density and viscosity.

Analyze major losses in pipes by calculating absolute roughness for materials, selecting fluid and diameter, and using the order number to determine the friction factor and pressure drop.
