Theoretical:
3.14×60×80=16320 (square centimeters)=1.63 (square meters)
3.14×(60÷2)? ×80=226080( Cubic centimeters) = 226 (liters)
Actual:
1. Brother, the data you provided is incomplete, because the solar water heater tank has an inner barrel and an outer barrel. There is a layer of insulation between them. The stainless steel area calculated above is for the outer box only, and you also need to take into account the steel plate used to wrap the outer box. The actual area must be greater than 1.63 square meters. to increase it by about 10%, which is enough. And the stainless steel materials of the inner and outer barrels are different, please pay attention
2. The water tank cannot hold that much water. For the reasons of the water tank inner and outer barrels mentioned above, the heat absorbing tube will be inserted into the water tank.Currently, 460 water tank and 480 water tank are more commonly used. on the market. Of course, there are other models as well. It just depends on your personal needs.
I hope this is helpful!
A solar water heater has a sealed cylindrical water tank. The cross-sectional diameter is approximately 60 cm and the length is 80 cm. How much does it take to make a water tank...
The disadvantages of ordinary flat panel wall-mounted solar water heaters are as follows:
They are seriously affected by the external climate and environment. When it is not available on rainy days, especially in winter, when the demand for domestic hot water is large, it brings great inconvenience to people's lives and other heating equipment is often required. Installation of additional electric heating installations in sola hot water tanksires is a commonly used method.
Wall-mounted solar water heaters also have their own limitations. Since the water tank is hung on the balcony, there are certain requirements for the size of the water tank, as well as whether the balcony can hang a solar water heater. flat panel sensor and the wall Whether the bearing capacity can withstand this is a question that needs to be considered. The national standard is that wall-mounted solar water tanks cannot exceed 80L. The main reason is that the wall of the. the part is not sufficiently load-bearing, so safety must be the first priority.
Secondly, the owner must first ask the owner if he or she agrees to install this type of solar energy. Wall mounted solar power is installed on the exterior wall. After installation, it may affect the overall beauty of the item. building. Many propertiess do not allow the homeowner to install this type of solar power. Additionally, wall-mounted solar water heaters are more complex than traditional solar systems and are more expensive than traditional solar water heaters. Of course, wall-mounted solar water heaters are also superior to traditional solar water heaters.
A solar water heater has a sealed cylindrical bucket with a bottom diameter of approximately 60 cm and a length of approximately 80 cm. Approximately how many square meters of stainless steel plates are needed to make this bucket (keep the number to two decimal places) How many liters of water can this bucket hold (keep the number in whole numbers)
The bottom diameter is approximately 60 cm, the radius = 30 cm
< p>Approximate number of steel plates needed to make this bucket = 3.14*30 *30*2+ 3.14*60*80=2826+15072
=17898 (square centimeters)
=1.7898 (square meters)
Approximately 2 meterssquares
This bucket can hold approximately 2 square meters of water = 3.14*30*30*80=226080 cubic centimeters=226.08 cubic decimeters=226.08 liters, or approximately 226 liters
