1.8 A water flow of 4.5 slug/s at 60 F enters the condenser of steam turbine and leaves at 140 F. Determine the heat transfer rate (Btu/hr)
Answer:
\(Hr=4.2*10^7\ btu/hr\)
Explanation:
From the question we are told that:
Water flow Rate \(R=4.5slug/s=144.78ib/sec\)
Initial Temperature \(T_1=60 \textdegree F\)
Final Temperature \(T_2=140 \textdegree F\)
Let
Specific heat of water \(\gamma= 1\)
And
\(\triangle T= 140-60\)
\(\triangle T= 80\ Deg.F\)
Generally the equation for Heat transfer rate of water \(H_r\) is mathematically given by
Heat transfer rate to water= mass flow rate* specific heat* change in temperature
\(H_r=R* \gamma*\triangle T\)
\(H_r=144.78*80*1\)
\(H_r=11582.4\ btu/sec\)
Therefore
\(H_r=11582.4\ btu/sec*3600\)
\(Hr=4.2*10^7\ btu/hr\)
what is the post processing for selective laser sintering (sls)?
Post processing for selective laser sintering (SLS) refers to the steps taken after the actual printing process to improve the quality and finish of the final product.
This includes removing excess powder, smoothing and polishing the surface, and dyeing or coating the part for aesthetic or functional purposes. Removing excess powder is important for ensuring accuracy and reducing the risk of contamination. This can be done through a variety of methods, including compressed air or vacuuming. Smoothing and polishing can be achieved through sanding or tumbling, while dyeing or coating can be used to add color, protect the surface, or improve the part's mechanical properties. Post processing is an essential step in the SLS process as it can significantly impact the final product's quality and durability. By carefully considering the necessary post processing steps, designers and manufacturers can ensure that their SLS parts meet their specific needs and requirements.

Ssume that the maximum torque that can be delivered to the workpiece by the lathe is 100 knm at 30 rpm. If the lathe is used to turn a steel component with a diameter of 3,400 mm and a specific machining energy of 4. 0 j/mm3, calculate the maximum achievable volumetric material removal rate. Show working and state your assumptions
The maximum achievable volumetric material removal rate is 78,500 mm3/s.
The maximum achievable volumetric material removal rate can be calculated using the following formula:
Volumetric Material Removal Rate (MRR) = (Torque) x (Angular Velocity) ÷ (Specific Machining Energy)
Where:
- Torque = 100 knm
- Angular Velocity = \(30rmp*\frac{2\pi }{60}\) = 3.14 rad/s
- Specific Machining Energy = 4.0 J/mm³
Plugging in the values into the formula, we get:
MRR = (100 knm) x (3.14 rad/s) ÷ (4.0 J/mm3)
MRR = 314 knm/s ÷ 4.0 J/mm³
MRR = 78.5 kmm³/s
To convert kmm³/s to mm³/s, we need to multiply by 1000:
MRR = 78.5 x 1000 mm³/s
MRR = 78,500 mm³/s
Therefore, the maximum achievable volumetric material removal rate is 78,500 mm³/s.
Assumptions:
- The maximum torque delivered to the workpiece is constant at 100 knm.- The specific machining energy of the steel component is constant at 4.0 J/mm³.- The diameter of the steel component is constant at 3,400 mm.Learn more about the maximum volumetric rate:

water flows steadily through a 2-in.-inside-diameter pipe at the rate of 200 gal/min. the 2-in. pipe branches into two 1-in.-inside-diameter pipes. if the average velocity in one of the 1-in. pipes is , what is the average velocity in the other 1-in. pipe?
Note that the average velocity in the other 1-in. pipe is approximately 3.996 times the average velocity in the first 1-in. pipe.
What is the definition of average velocity?Average velocity is the displacement of an object over a given time interval, divided by the time interval. It is a vector quantity with both magnitude and direction.
We can start by using the principle of continuity, which states that the mass flow rate (ρAV) of an incompressible fluid is constant throughout a pipe of varying cross-sectional area (where ρ is the density of the fluid, A is the cross-sectional area, and V is the average velocity).
Since the water flows steadily through the 2-in. pipe at the rate of 200 gal/min, we can convert the flow rate to SI units:
200 gal/min * (1 ft³/gal) / (60 s/min) * (3.785 L/gal) / (1 ft³) = 0.4731 m³/s
The cross-sectional area of the 2-in. pipe can be calculated using its inside diameter:
A1 = πd1²/4 = π(2 in./12)²/4
= 0.000871 m²
The cross-sectional area of each 1-in. pipe can be calculated similarly:
A2 = πd2²/4 = π(1 in./12)²/4
= 0.000218 m²
Since the mass flow rate is constant, we can set the mass flow rates for the two 1-in. pipes equal to the mass flow rate for the 2-in. pipe:
ρA1V1 = ρA2V2
Dividing both sides by ρ gives:
A1V1 = A2V2
Substituting the values we have calculated:
0.000871 m² * V1
= 0.000218 m² * V2
Solving for V2:
V2 = (0.000871 m² / 0.000218 m²) * V1
= 3.996 * V1
Therefore, the average velocity in the other 1-in. pipe is approximately 3.996 times the average velocity in the first 1-in. pipe.

A nonpipelined system takes 300ns to process a task. The same task can be processed in a 5-segment pipeline with a clock cycle of 60ns. Determine the speedup ratio of the pipeline for 100 tasks. What is the maximum speedup that could be achieved with the pipeline unit over the nonpipelined unit
Answer:
The maximum speedup that could be achieved is approximately 4.81.
Explanation:
From the question, we have:
Speed up ratio = Time taken by a non-pipelined processor / Time taken by a pipelined processor = (n * T) / ((n + (k – 1)) * Tk) …………………. (1)
Where:
n = number of tasks = 100
T = Number ns for a nonpipelined system takes to process a task = 300
k = Type of segment pipeline = 5
Tk = Number of clock cycle of the type of segment pipeline in ns = 60
Substituting the above into equation (1), we have:
Speed up ratio = (100 * 300) / ((100 + (5 - 1)) * 60) = 4.81
Therefore, the maximum speedup that could be achieved is approximately 4.81.

if a constructor is not written when the class is compiled, then a constructor is automatically provided and it is known as the default constructor.
If a constructor is not explicitly written in a class, a default constructor is automatically provided by the compiler. In object-oriented programming, a constructor is a special method that is used to initialize objects of a class.
When a class is compiled, if no constructor is defined by the programmer, the compiler automatically generates a default constructor for that class. The default constructor has the same name as the class and does not have any parameters. The purpose of the default constructor is to initialize the object's state with default values or perform any necessary setup operations. It is called implicitly when an object is created using the class's constructor. The default constructor can be useful when no specific initialization logic is required or when the class does not have any fields that need initialization. If a constructor is explicitly defined by the programmer, the default constructor is not generated by the compiler. However, if no constructor is defined, the default constructor allows the class to be instantiated without any arguments. It provides a fallback option for object creation and ensures that objects of the class can be created even if a custom constructor is not provided.

You are designing a package for 200 g of snack food that is sensitive to oxygen, and fails when it absorbs 120 ppm of oxygen (by weight). Marketing tells you it wants the snack to be in a plastic pouch measuring 6 inches by 6 inches (ignore seems), so it will have a total surface area available for permeation of 72 in(6" x 6" x 2 sides). You need to recommend an appropriate plastic material for this product, to provide a minimum of 70 days shelf life. Follow these steps:
a. Calculate the allowable oxygen gain, in cm at STP. (5 pts)
b. At this point, you do not know the material you will use, so you do not know the permeability coefficient or the thickness. The better the barrier the plastic you choose, the thinner the material can be to provide the appropriate barrier. Rather than simple trial and error, a sensible approach is to solve for the ratio of P/L that is required. We can solve the basic permeability equation for this ratio: P = 9 At Ap L Use the information you have to determine the required value for P/L, expressing your answer in cm/(100 in? d atm). (5 pts)
c. Use the information in the textbook (chapters 4 and 14 or in another reliable source; provide reference if you have used chapter 4, 14 or any other source) on oxygen permeability coefficients for various polymers to select a polymer that would be suitable, and calculate the required thickness. (Be sure this is reasonable; for example, if the required thickness is more than 20 mils, you need to choose a different polymer!) Note that chapter 4 presents these values in the units you used in (b) while chapter 14 presents values with different units, so unit conversion would be required. In your answer, state the material you have chosen, its oxygen permeability coefficient, and the minimum thickness you recommend. (Be sure to express the thickness with no more than one decimal place.) Obviously, there is more than one solution to this problem, but you only need one. (10 pts)

Using trig work out h and w.
h = 10 sin ?
w = 10 cos ?
A = 10h + hw

Differentiate the expression (either use the product rule for sin? cos?, or write 100sin?cos? as 50sin2? using the double angle formula)
A = 100sin? + 50sin2?
dA/dt = 100cos? + 100cos2?
For A to be a max or min the derivative must equal zero
100cos? + 100cos2? = 0
cos? + cos2? = 0
Use the double angle formula to write cos2? as 2cos^2 ? - 1
cos? + 2cos^2 ? - 1 = 0
2cos^2 ? + cos? - 1 = 0
This quadratic factorizes:
(2cos? - 1)(cos? + 1) = 0
This means that
cos ? = 1/2 or cos ? = 1
giving:
? = pi/3 or ? = pi
Which means that to achieve the maximum area ? should be pi/3 = 60 degrees
You can check that this is the max by substituting in these values of theta and the two end points (theta = 0, theta = pi), and seeing that pi/3 gives the maximum.
The maximum area is therefore
A = 100sin? + 100sin?cos?

Literature Review Discuss the importance of lubrication in rolling-contact and journal bearings. Comment on the desired physical and chemical characteristics of lubrication in bearings for the following applications: Automatic Transmission of a Car Engine components Marine, or off-shore Applications
Rolling-contact and journal bearings are widely used in mechanical systems for efficient and safe operations. The importance of lubrication in these bearings cannot be overstated, as it reduces friction between the surfaces and minimizes wear and tear. This ensures that the bearings function optimally.
A literature review is a comprehensive analysis of literature or research publications that relate to a specific topic or question. In this case, we are reviewing published research and literature on the importance of lubrication in rolling-contact and journal bearings.
Lubrication plays a crucial role in the functioning of rolling-contact and journal bearings. Some of the essential functions of lubrication include reducing friction between surfaces in contact, minimizing heat generated by friction and reducing the chances of overheating, providing a layer of protection against corrosion and rust, and acting as a coolant for bearings that generate a lot of heat.
Bearing lubricants should have specific physical and chemical characteristics depending on the application. For instance, transmission fluids should have a high viscosity to provide the necessary lubrication and protect the gears from wear and tear. They should also have excellent thermal stability to perform effectively at high temperatures and prevent the formation of sludge and other deposits.
Engine oils should have excellent anti-wear additives that reduce wear and tear on engine components. They should also have good detergency to keep the engine clean and prevent the formation of deposits. Additionally, they should have low volatility to prevent excessive oil consumption and reduce emissions.
For marine or offshore applications, lubricants should have good water separation properties to prevent the formation of rust and other deposits. They should also have good rust protection properties and be biodegradable to minimize the impact on the environment.
In summary, lubrication is vital for the efficient and safe functioning of rolling-contact and journal bearings. Lubricants should have specific characteristics depending on the application, and a literature review can provide valuable insights into the importance of lubrication in these bearings.
