Answer:

False

Explanation:

According to the American National Standard for Engineering Drawings, there are ten (10) different types of lines used in engineering drawings to communicate important information about the item. Some of these lines could either be thick or thin. These include the following:

1. Visible Line

2. Hidden Line

3. Section Line

4. Center Line And Symmetry Line

5. Dimension Line Extension Line And Leader

6. Cutting-Plane Line Or Viewing-Plane Line

7. Break Line

8. Phantom Line

9. Stitch Line

10. Chain Line

dimulka [17.4K]

Answer:

Space velocity = 30 hr⁻¹

Explanation:

Space velocity for reactors express how much reactor volume of feed or reactants can be treated per unit time. For example, a space velocity of 3 hr⁻¹ means the reactor can process 3 times its volume per hour.

It is given mathematically as

Space velocity = (volumetric flow rate of the reactants)/(the reactor volume)

Volumetric flowrate of the reeactants

= (molar flow rate)/(concentration)

Molar flowrate of the reactants = 300 millimol/hr

Concentration of the reactants = 100 millimol/liter

Volumetric flowrate of the reactants = (300/100) = 3 liters/hr

Reactor volume = 0.1 liter

Space velocity = (3/0.1) = 30 /hr = 30 hr⁻¹

Hope this Helps!!!

soldier1979 [14.2K]

A vector is a phenomenon which in mostly used in mathematics and physics and is related to direction and size.

<u>Explanation:</u>

In mathematics and physics, a vector is a component of a vector space. For some, particular vector spaces, the vectors have gotten explicit names, which are recorded beneath. Verifiably, vectors were presented in geometry and material science before the formalization of the idea of vector space.  

A vector is an amount or phenomenon that has two autonomous properties: magnitude and direction. The term likewise means the numerical or geometrical portrayal of such an amount.
