Answer:
B. The thickness of the heated region near the plate is increasing.
Explanation:
First we know that, a boundary layer is the layer of fluid in the immediate vicinity of a bounding surface where the effects of viscosity are significant. The fluid is often slower due to the effects of viscosity. Advection i.e the transfer of heat by the flow of liquid becomes less since the flow is slower, thereby the local heat transfer coefficient decreases.
From law of conduction, we observe that heat transfer rate will decrease based on a smaller rate of temperature, the thickness therefore increases while the local heat transfer coefficient decreases with distance.
Answer:
Enthalpy, hsteam = 2663.7 kJ/kg
Volume, Vsteam = 0.3598613 m^3 / kg
Density = 2.67 kg/ m^3
Explanation:
Mass of steam, m = 1 kg
Pressure of the steam, P = 0.5 MN/m^2
Dryness fraction, x = 0.96
At P = 0.5 MPa:
Tsat = 151.831°C
Vf = 0.00109255 m^3 / kg
Vg = 0.37481 m^3 / kg
hf = 640.09 kJ/kg
hg = 2748.1 kJ/kg
hfg = 2108 kJ/kg
The enthalpy can be given by the formula:
hsteam = hf + x * hfg
hsteam = 640.09 + ( 0.96 * 2108)
hsteam = 2663.7 kJ/kg
The volume of the steam can be given as:
Vsteam = Vf + x(Vg - Vf)
Vsteam = 0.00109255 + 0.96(0.37481 - 640.09)
Vsteam = 0.3598613 m^3 / kg
From the steam table, the density of the steam at a pressure of 0.5 MPa is 2.67 kg/ m^3
Options: True or false
Answer:True, it will be called CRMWRONGEDLP.
Explanation:eNotes was founded in 1998 by Brad Satoris and Alexander Bloomingdale, to enable and enhance the ability of students to solve assignments as given and other home works,eNote is also used by students to prepare effectively and efficiently for examinations.
Since its launch eNote has been a great source of educational materials for students who have gained a lot in the use of its materials.
bullwhip effect is a concept in supply chain, where forcasts causes the supply chain to be inefficient, it usually starts from retailers who raise concern of high demands.
CRMWRONGEDLP, is the program that minimizes the bullwhip effects according to eNote.
Answer:
Cause and effect
Explanation:
In this text, the most suitable structure is a cause and effect structure. The text explains why the prices of economy cars rose substantially in the United States during the mid-1980s. The initial cause was import quotas, which led to the effect of the Japanese sending mostly luxury cars to America. This pattern is reproduced through the passage, allowing us to understand the connection between different sentences within a paragraph.
Answer:
Option c)
Explanation:
a.The carbon content of eutectoid steel, which is an carbon- iron alloy, is in between 0.80-0.83%
b. In hypoeutectoid steel, the carbon composition is less than 0.80% and is approximately 0.76%
c. In hypereutectoid steel, the carbon composition ranges from 0.80% - 2.0%
d. In wrought iron, the iron composition is quite low about 0.08%
