A-Air at a temperature of 134°C and atmospheric pressure flows with a velocity of 7 m/s over a smooth 5 m long and 1 m wide cast iron plate. Under steady-state conditions, the air-side

surface temperature of the plates is at 120°C. Under the described conditions, determine the

overall heat transfer rate through the plate.

B-If the flat plate in (A) is replaced with a cylinder with the same surface area (heat transfer

area) and the cylinder's length is the same as the width of the plate (1.0 m), what would be the

heat transfer rate for cross air flow over the outside surface of the cylinder?

C. If the flat plate in (A) is replaced with a sphere with the same surface area (heat transfer area),

what would be the heat transfer rate for cross air flow over the outside surface of the sphere?

D- Based on your results, discuss which surface configuration is more effective for heat

dissipation and why.

Which of the following statements concerning the influence of culture on ethnic identity formation is accurate? a. one will reject ethnic identity if cultural stereotypes are encountered. b. if one’s ethnic city is different from the dominant cultural group, then one’s ethnic identity you will become weekend. c. if an the ethnic group is excepted by dominant culture, then ethnic identity formation can be a difficult process. d. similarity to the dominant culture can determine how easy it is for one to except ethnic differences.

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback
