What type of Exhaust is best for the 3.9 Mopar V6 Engine in Dodge Dakota?

Air is to be compressed so that its volume is reduced to half of its original volume if the initial pressure is 200 kPa and the

Alex_Xolod [135]

Answer:

$P_{2} = 527.803\,kPa$

Explanation:

The politropic relationship for a isentropic process is:

$\frac{P_{2}}{P_{1}} = \left(\frac{V_{1}}{V_{2}} \right)^{\gamma}$

Where $\gamma$ is the ratio of specific heats

The final pressure is:

$P_{2} = P_{1}\cdot \left(\frac{V_{1}}{V_{2}}\right)^{\gamma}$

$P_{2} = (200\,kPa)\cdot (2)^{1.4}$

$P_{2} = 527.803\,kPa$

A capillary tube is immersed vertically in a water container. Knowing that water starts to evaporate when the pressure drops bel

Anuta_ua [19.1K]

Answer:

$d=0.414\times 10^{-4}\ m$

Explanation:

Given that

P = 4 KPa

Contact angle = 6°

Surface tension = 1 N/m

Lets assume that atmospheric pressure = 100 KPa

Lets take that density of water = $1000\ kg/m^3$

So the capillarity rise h

$h=\dfrac{\Delta P}{\rho g}$

$h=\dfrac{100\times 1000-4\times 1000}{1000\times 10}$

h= 9.61 m

We know that for capillarity rise h

$h=\dfrac{2\sigma cos\theta }{r\rho g}$

$r=\dfrac{2\sigma cos\theta }{h\rho g}$

$r=\dfrac{2\times 1 cos4^{\circ} }{9.61\times 1000\times 10}$

$r=0.207\times 10^{-4}\ m$

$d=0.414\times 10^{-4}\ m$

Suggest suitable materials of construction for the following applications and provide justifications.

Sergio039 [100]

Answer:

a) 316 stainless steel

b) 316 stainless steel

c) Carbon steel

d) stainless steel 316

e) stainless steel 316

f ) Carbon steel

Explanation:

A) A 10,000 M' storage tank for Toluene

The best material for building this tank is 316 stainless steel this is because it is relatively cheaper than other materials such as Hest Alloy C while still maintaining the required tensile strength needed to build the storage tank for Toluene

B) A 5.0 m' tank for storing a 30% w/w aqueous solution of sodium chloride

The suitable material for building this tank is 316 stainless steel as it is cheaper than Titanium and Hest Alloy C and it is compatible with sodium chloride

C) A 2 m diameter, 20 m high distillation column, distilling acrylonitrile

The best material for constructing this column is Carbon steel and this is because it has a very high compressive strength which is approximately . 1320 MPa

D) A 100 m storage tank for strong nitric acid.

The best material is stainless steel 316 and this is due to its high tensile strength

E) 316 stainless steel

F) Carbon steel is suitable for building this absorption column because it has a very high compressive strength which is approximately . 1320 MPa
