You currently have an electric hot water tank to produce your domestic hot water, which operates at 95% efficiency, and consumes 25 GJ of electricity to per year. You get a new hot water tank, this time, it comes with an integrated heat pump water heater with an annual COP of 2. Assume:
- Hot water load evenly distributed every month
- Heat for heat pump is drawn from space around hot water tank, which is located in the house.
- Losses of the original tank were heat losses from the tank to its surrounding air.
- Space heating is required 4 months of the year.
- Cooling is required for 6 months per year.
How much energy does the new hot water tank consume? By approximately how much would the space heating and cooling energy demand change with the new tank?

Suppose you have an electric hot water heater for your house which is an aluminum cylinder which has a 0.56 m radius and is 2 m high. The walls are 1.0 cm thick. The thermal conductivity of Aluminum is 217 W/(m K). Assume that the temperature of the hot water inside the hot water heater is kept at a constant 90 C, and the external temperature is 27 C. Part A: What is the surface area of the cylinder? Part...

In large buildings, hot water in a water tank is circulated through a loop so that the user doesn’t have to wait for all the water in long piping to drain before hot water starts coming out. A certain recirculating loop involves 300-foot-long, 1-inch--diameter PEX pipes with six 90° threaded smooth bends and two fully open gate valves. The PEX piping is considered to be smooth (roughness is 0). If the average flow velocity through the loop is 5 ft/s,...

The Florida Energy Factor (FEF) is used to compare the efficiency of domestic solar hot water heaters and to determine certain building construction credits. Solar water heaters with a high FEF are more cost efficient. Assume normality for the FEF distribution. A random sample of approved heaters was obtained, and the FEF value for each is given in the following: 3.3 3.2 1.8 2.1 4.2 3.9 4.6 6.3 1.9 1.9 4.9 6.7 5.2 3.1 1.4 Is there any evidence to...

Electro Motors (Electro) is considering a new project to produce electric vehicles for the Australian domestic market and international markets. It has identified a property/plant that was formerly used to build petrol fuelled motor vehicles that could be refitted at minimal cost to manufacture the new electric vehicles. Electro is targeting Australian metropolitan centres for initial sales and expanding into regional centres over the next five years. International demand for electric vehicles is being driven by China and Electro has...

My hot water system maintains a volume of 200L of water, which it heats at a rate of 1 ◦C per minute, up to a maximum temperature of 60◦C. On a winter's morning, the tank is full of water at this maximum temperature. While the shower is on, the tank is relled with water from the cold water source, which is at 10◦C. Assume the water in the tank maintains a uniform temperature (because is well-mixed). In my shower, the...

In the figure, the top tank, which is open to the atmosphere, contains water and the bottom tank contains oil covered by a piston. The tank on the right has a freely movable partition that keeps the oil and water separate. The partition is a vertical distance 0.10 m below the open surface of the water. If the piston in the bottom tank is 0.50 m below the open surface of the water and has a surface area of 8.3...
