A liquid phase chemical reaction (A → B) takes place in a well-stirred tank. The concentration of compound A in the feed is CA0

(mol/m3 ), and that in the outlet stream is CA (mol/m3 ). Neither concentration varies with time. The volume of the tank contents is V (m3) and the volumetric flow rate of the inlet and outlet streams is Ẇ (m3 /sec). The reaction rate (the rate at which A is consumed by reaction in the tank) is given by the expression r (mol A consumed/s) = kVCA wherek is a constant.
(a) Is this process continuous, batch, or semi batch? Is ittransient or steady - state?(b) What would you expect the reactant concentrationCA to equal if k = 0 (no reaction) ? What should itapproach if k [infinity] ( infinitely rapid reaction) ?(c) Write a differential balance on A, starting which terms inthe general balance equation ( accumulation = input + generation -output - consumption) you discarded and why you discarded them. Usethe balance to derive the following relation between the inlet andoutlet reactant concentrations :CA = CA0 / (1 + kV/ ). Verify that this relation predicts the results in part(b).

What is a splitter gearbox​
OLga [1]

Answer:

The splitter transmission also uses a high-low division. Instead of having a high and low section, the gears are split into two so that each position of the gear shift is used for two gears (one high and one low).

Consider a circuit element, with terminals a and b, that has vab= -12V and iab= 3A. Over a period of 2 seconds, how much charge
miv72 [106K]

Answer:

a) 6 coulombs

b) The electrons carrying the charge will enter at point b with respect to element and this is because electrons follow in opposite direction of current

c) = -72 joules

Energy is taken from element

Explanation:

Given data:

V ab = -12 v

I ab = 3A

period ( t ) = 2 seconds

a) determine how much charge moves through the element

q = I * t

  = 3 * 2 = 6 coulombs

b) The electrons carrying the charge will enter at point b with respect to element and this is because electrons follow in opposite direction of current

c) determine how much energy is transferred

= Vab * Iab * t

= -12 * 3 * 2

= -72 joules

Energy is taken from element

In your opinion, what is the external opportunity cost of a successful biking company in a community
OleMash [197]

Answer:

The cost of increased rates of accidents/injuries due to road accidents associated with cycling.

Explanation:

Opportunity cost is referred to as an alternative cost which is the value of the other choose left out while settling for a better alternative. External cost will be the cost a society has to bear as a result of a private cost. A successful biking company in a community can led to increased rates of accidents due to road accidents associated with cycling. In addition, the society will have to bear the costs of the threats presented by dangerous car drivers who posse more danger to cyclists as compared to trucks/car drivers.

Explain why the scenario below fails to illustrate an understanding of the importance of metrology. Situation: Natalie is a cali
VMariaS [17]

Answer:

Explanation:

The situation being described completely fails in regard to the importance of metrology. This is because the main importance of metrology is making sure that all of the measurements in a process are as accurate as possible. This accuracy allows an entire process to function efficiently and without errors. In a food production plant, each individual department of the plant relies on the previous function to have completed their job with the correct and accurate instructions so that they can fulfill their functions correctly and end up with a perfect product. If the oven (like in this scenario) is a couple of degrees off it can cause the product to come out burned or undercooked, which will then get transferred to the next part of production which will also fail due to the failed input (burned or undercooked product). This will ultimately lead to an unusable product at the end of the process and money wasted. Which in a large production plant means thousands of products in a single batch are thrown away.
