1. Is the floe within the pipe turbulent or laminar? Justify
your answer
2. What is the average Nusselt number and heat transfer
coefficient in the pipe? You can assume that the flow is fully
developed
3. What length of pipe is required to achieve the desired exit
temperature?
4. Was your assumption of fully developed flow justified?
Explain why or why not. How much error did this assumption
introduce into calculation of nusselt number? Do you need more or...

1. At an outdoor lot, there is a black-colored solar heat collection copper pipe. It is 50 meters long, 10 cm in inner diameter and 10.2 cm in outer diameter. The pipe is set horizontally. Assume that solar radiation in 1.0 kW/m2 shines on the entire surface of the pipe and convert 90% of the solar energy on the pipe into heat. There is water in 25...
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
