Problems associated with hard water include: formation of scale, mineral deposits in water heaters (which reduces efficiency and increases heating costs), increases detergent usage, formation of soap curds, and yellowing of linen.

Describe the geothermal energy system that does not rely on hot springs. Describe how it could be used to heat and cool a building. What are their potential drawbacks that prevent it from being more widely used?

1. Heating - Using the heat from hot water or steam trapped in the earth. Problems with hydrogen sulfides and corrosive salts. 2. Cooling - Pipes are run underground below the frost line. Water is circulated through the pipes then brought back inside the building where it is used to cool the building. It can also be used as a heat source for a heat pump and used to warm the building in the winter. 3. Problems - The traditional method requires a large amount of land to be functional. Drilling is very expensive and single use adversely affects the aquifer.

Describe the causes, symptoms, and solutions for the following piping problems 1. Vibration Noise 2. Water Hammering 3. Pipe Expansion

1. Vibration Noise - This is due to pipe contact with a vibration source, such as a pump. This can be controlled by cutting the pipe and installing a rubber connector. 2. Water Hammering - This is the most dangerous problem. It can literally shake your pipes apart. Water hammering is due to the sudden change in pressure in the pipes. It is most often caused by a valve closing too fast. Protect by adding a length of capped vertical pipe extending upwards. 3. Pipe Expansion - This is most often due to changes in pipe temperature. Can be controlled by insulating pipes and using a circulating pump.

What do each of the following units measure? 1. Watts 2. Volts 3. Amperes 4. Kilowatt-hours

1. Watts are a measure of power. Power is energy used per unit of time. Watt = Voltage*Current (P = V* I) 2. Volts are a measure of electrical potential. Electrical potential is the driving force that causes electricity to flow. 3. Amperes are a measurement of current. Amps = Volts / Resistance (I = V / R) Main use is to size wire and circuit breakers. There is generally a factor of safety taken into account when sizing the wire and circuit breakers. The normal load is generally only 75% of the rated capacity. 4. Kilowatt-hours are a measurement of energy and is typically the basis for electric energy charges. Kwh = Kilowatts * time consumed in hours

What is an indirect drain, what is its purpose, and where is it commonly used?

Uses an air gap to prevent water from backing up into the sink.

Describe the Upfeed water-distribution system

Water enters the building at ground level and travels up to where it is needed. If supply pressure is not efficient to reach upper floors, it must be augmented with a pump. For tall buildings, the pressure needed to raise the water to the upper floors makes this system cost prohibitive, both in the pump required and the thickness of the pipes.

What are the advantages and disadvantages associated with circulating pump distribution systems?

Water is constantly flowing in the pipes due to the use of a pump. It can be used with either an upfeed or downfeed system. This system is normally only used for hot water pipes. It offers several advantages over the non-circulating systems -It provides instant hot water to all fixtures Compared to small pipe systems: it provides constant. Compared to large pipe systems: it uses smaller pipes. Disadvantages: They generally cost more to operate due to maintenance and energy costs related to the pump. They also have higher heat losses through the pipe walls.

Describe the Downfeed water-distribution system

Water is pumped to a tank above the point where it is needed. Pressure is created by the height of the water in the tanks above the fixture. For tall buildings, a series of tanks will be used to ensure safe pressure on all floors.
