A pipe with an internal diameter of 2.0 cm carries water to the basement of a house at a speed of 0.90 m / s with a pressure of 150 kPa. If the pipe narrows to 1.2 cm and rises to the second floor, 8.2 m above the point of entry, what is the water pressure on the second floor? (Consider acceleration of gravity equal to 10 m / s² and water density equal to 10³kg / m³) a. 16,8...
A steel pipe (AISI 1010) carries a water stream of temperature T_w = 4 C. It functions in a cold climate, the effect of which is to lower the outer pipe wall temperature to T_s,o = ?10 C. A cylindrical sheet of ice builds on the inside of the pipe. The inner diameter of the pipe is D_i = 80cm, the wall thickness of the pipe is t = 1cm and the convective heat transfer coefficient at the inner surface...
4. A pure copper pipe with inner diameter Di-10 mm ard outer diameter Do-14 mm is surrounded by saturated steam with pressure p 172 bar and convection coefficient h 6000 carries water with mean velocity u- (a) Determine the convective heat transfer coefficient inside the pipe for water at mean temperature Tm 37° C (b) At this same location, determine the total thermal resistance (per unit length) between the water and the steam. (c) Determine the heat transfer rate (per...
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....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...

FISCAL POLICY IN THEORY: March, 2020: we are on the verge of Congress and the President passing legislation that will empower the federal government to spend an unprecedented amount of EXTRA money not seen since World War 2 ---- in order to address the pandemic but also to help cushion the blow financially of perhaps ten or twenty million Americans --- or more --- losing their jobs, and thus suffering a drop in income. The scale of the 2020 recession...
