Answer:

**Answer:**

**Explanation:**

mole fraction of propane after passing through the separator is

mole fractions of ethane and methane after passing through separator are:

Change in partial pressures then can be written as:

where and are mole fractions after and before passing through the separator

Hence,

Benzene vapor at 480°C is cooled and converted to a liquid at 25°C in a continuous condenser. The condensate is drained into 1.75-m3 drums, each of which takes 2.0 minutes to fill. Calculate the rate (kW) at which heat is transferred from the benzene in the condenser.

**Answer**

Given,

Reservoir pressure of a supersonic wind tunnel = 5 atm

Local Mach number = ?

Area ration = ?

a) 4 atm.

Pressure ratio =

= 0.8

From Isentropic Flow Tables

M = 0.58 A/A* = 1.213

b) 2.64 atm

Pressure ratio =

= 0.528

From Isentropic Flow Tables

M = 1 A/A* = 1

c) 0.5 atm

Pressure ratio =

= 0.1

From Isentropic Flow Tables

M =2.10 A/A* = 1.8369

(A) contouring

(B) roughing out

(C) forming

(D) tapping out

**Answer:**

tapping out I think sorry if I'm wrong

**Answer:**

3 m/s²

**Explanation:**

Acceleration is calculated as :

a= Δv/ t

where ;

Δv = change in velocity

Δv = 45 - 0 = 45 m/s

t= 15 s

a= 45 /15

a= 3 m/s²

**Answer and Explanation:**

The computation is shown below

**Total average cost + total variable cost = total cost**

Let number of output be x

So,

Total fixed average cost = x × $30

Total variable cost = x × $15

Total cost = $2,500

Therefore,

$20 × x + $30 × x = $2,500

50 × x = $2,500

**x = 50**

Now the total variable cost is

= 50 × $20

= **$1,000**

And, the fixed cost is

= 50 × $30

= **$1,500**

**Answer:**

12 4

**Explanation:**

because the production average is variable

**Answer:**

(B) Because rotating shafts are used in engineering applications

(C) We don't care - simply an academic exercise.

(D) Because it can determine G and inform us of a materials ability to resist shear deformation

**Answer:**

(A) Because the angle of twist of a material is often used to predict its shear toughness

**Explanation:**

In engineering, torsion is the solicitation that occurs when a moment is applied on the longitudinal axis of a construction element or mechanical prism, such as axes or, in general, elements where one dimension predominates over the other two, although it is possible to find it in diverse situations.

The torsion is characterized geometrically because any curve parallel to the axis of the piece is no longer contained in the plane initially formed by the two curves. Instead, a curve parallel to the axis is twisted around it.

The general study of torsion is complicated because under that type of solicitation the cross section of a piece in general is characterized by two phenomena:

1- Tangential tensions appear parallel to the cross section.

2- When the previous tensions are not properly distributed, which always happens unless the section has circular symmetry, sectional warps appear that make the deformed cross sections not flat.
