Answer:

It improves problem solving abilities and conceptualization
Creates a competitive edge or approach to research problems
It is vital for quality assurance and testing

Explanation:

When designing a solution to a problem, an engineer performs a research first in the area of problem. This will include understanding other works done by various individuals on similar topics. This shades light to the engineer on the concept of study and challenges him or her to think critically and develop a better solution concerning a problem. When the problem solving abilities are challenged, an engineer could come up with a better solution to a problem in terms of the technology applied and innovations to adjust to as a company thus putting the firm, products, customers and the entire economy at a better place than before in terms of problem solving approaches and solutions. Furthermore, research will offer a chance for quality control which is vital for success of a business in the production of products which meets or surpass users expectations.

It is possible to maintain a pressure of 10 kPa in a condenser that is being cooled by river water entering at 20 °C?

vovangra [49]

Answer:

Yes, it is possible to maintain a pressure of 10 kPa in a condenser that is being cooled by river water that is entering at 20 °C because this temperature (20 °C) of the external cooling water is less than the saturation temperature of steam which is which is 45.81 °C, and heated by a boiler; as a result of this condition, coupled with the assumption that the turbine, pump, and interconnecting tube are adiabatic, and the condenser exchanges its heat with the external cooling river water, it possible to maintain a pressure of 10 kPa.

zhannawk [14.2K]

Answer:

Option A

Explanation:

As per the article "Time Travel Is A Fun Science Fiction Story But Could It Be Real?" the gravitational field is a representation of curving space and time. As the gravity becomes strong, the space-time get more curved and hence the time gets slower.

Hence, option A is correct

Consider water at 27°C in parallel flow over an isothermal, 1‐m‐long flat plate with a velocity of 2 m/s. a) Plot the variation

yulyashka [42]

Answer:

i) h-bar-L = 4110 W/m^2K

ii ) h-bar-L = 4490 W/m^2K

iii) h-bar-L = 5072 W/m^2K

Explanation:

Given:-

- The temperature of water, T = 27°C

- The velocity of fluid flow, U∞ = 2m/s

- The length of the flat place, L = 1 m

Solution:-

- Using table A-6, to determine the properties of water:

Density ρ = 997 kg/m^3

Dynamic viscosity ν = 0.858*10^-6 m^2/s

Pr = 583 , k = 0.613 W/m.K

- The reynold's number for full length (L = 1m):

Re = U∞*L / ν

Re = (2)*(1) / (0.858*10^-6)

Re = 2.33*10^6

- The boundary layer is mixed with Rex,c = 5*10^5. Evaluate the critical length (xc):

xc = L* ( Rex,c / Re )

= (5*10^5 / 2.33*10^6 )

= 0.215 m

a) Using "IHT correlation tool, External Flow, Local coefficients for laminar or Turbulent flows", h (x) was evaluated and plotted with critical Reynolds number for all 3 cases: (i) 5 × 10^5, (ii) 3 × 10^5, and (iii) 0 (the flow is fully turbulent). - (See attachment 1)

b) Using "IHT correlation tool, External Flow, Average coefficients for laminar or Mixed flows", h - bar- (x) was evaluated and plotted with critical Reynolds number for all 3 cases: (i) 5 × 10^5, (ii) 3 × 10^5, and (iii) 0 (the flow is fully turbulent). - (See attachment 2)

c) The average convection coefficient for the plate can be determined from the graphs presented in (Attachments 1 and 2). Since,

h-bar-L = h-bar-x(L)

The values for the flow conditions are:

( i) h-bar-L = 4110, ii ) h-bar-L = 4490 , iii) h-bar-L = 5072 ) W/m^2K
