Steam Generator air (inlet) - 320°C P. = 100 kPa th =0.5 kg/s heat exchanger - water (inlet) T = 20°C Pw = 100 kPa m = 0.025 kg/s Problem sketch Solve with EES. Document all necessary balances The problem sketch illustrates a heat exchanger in which hot air is used to generate steam. Air enters the heat exchanger at 1a, in = 320C, Pa = 100 kPa, and ma -0.5 kg/s. Model air as an ideal gas with constant...

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...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...

What an Executive Summary Is
An executive summary is a specific type of document that does
two things: it summarizes a research article, and it offers
recommendations as to how information from the article can be
used.
Some long reports can contain an executive summary section, as
indicated in the Pearson handbook.
