Case 1: Material system without density and viscosity differences Though unlikely in real life, in this case, we assume that all of the material in the homogenizer is of the same density and viscosity. Thus, only one set of material parameters are mentioned (density, ρ; dynamic viscosity, μ). The important parameters are listed as follows: Target quantity : Mixing time, θ Geometric parameters : Stirrer diameter, d Material parameters : Density, ρ Dynamic viscosity, μ Process-related parameters : Stirrer speed, n 1.1) Write out the relevance list for Case 1. 1.2) Generate the pi-set for this case. 1.3) Write out the appropriate pi (π) numbers from the generated pi-set. 1.4) Identify the established dimensionless numbers from the derived pi (π) numbers. 1.5) Write the possible relationship of the dimensionless numbers for Case 1.
In the field of air pollution control, one often needs to sample the quality of a moving airstream. In such measurements a sampling probe is aligned with the flow as sketched in Fig. A suction pump draws air through the probe at volume flow rate V· as sketched. For accurate sampling, the air speed through the probe should be the same as that of the airstream (isokinetic sampling). However, if the applied suction is too large, as sketched in Fig, the air speed through the probe is greater than that of the airstream (super iso kinetic sampling). For simplicity consider a two-dimensional case in which the sampling probe height is h = 4.58 mm and its width is W = 39.5 mm. The values of the stream function corresponding to the lower and upper dividing streamlines are ?l = 0.093 m2/s and ?u = 0.150 m2/s, respectively. Calculate the volume flow rate through the probe (in units of m3/s) and the average speed of the air sucked through the probe.
explains how the two methods of parameter estimation, namely the method of parameter estimation and the method of moments and percentile matching, are used to fit distributions to data for actuarial calculations.
You are the mechatronics engineer of a manufacturing plant. You decide to perform an analysis on a robot arm of the assembly line with the objective of optimizing its performance. After taking several readings of the speed of the arm’s end effector, you approximate its velocity to the function given below. v(t) = -t4 + 5t3 - 7t2 + 3t + 0.22 0 =< t =< 3 where the velocity is in ms-1 Use your knowledge of differentiation to sketch the velocity-time graph, clearly marking the critical points. Using the graph sketched in (a) above, estimate the velocity when t = 1.5 s Calculate the velocity of the function when t = 1.5 s by substituting to the velocity function. Compare this value to the value you estimated in b above.
Simulation Accuracy and Typical Faults When modelling systems, many assumptions have to be made. These can lead to erroneous results, affecting accuracy. Determine the likely faults that can arise from the application of simulation techniques. By evaluating modelling methods, discuss these methods and evaluate the data accuracy, both in terms of model development and results analysis. Looking at the CFD model of the electric car in Assignment 3, explore in detail the relevant information from one of the simulations undertaken. By tracing potential faults in the application of the simulation technique undertaken, discuss what these could be and how improvements could be made to improve the model and simulation.
A one-fortieth-scale model of a ship’s propeller is tested in a tow tank at 1250 r/min and exhibits a power output of 1.9 ft·lbf/s. According to Froude scaling laws, what should the revolutions per minute of the prototype propeller be under dynamically similar conditions? According to Froude scaling laws, what should the horsepower output of the prototype propeller be under dynamically similar conditions?

The processing of raw coal involves “washing,” in which coal ash (nonorganic, incombustible material) is removed. The article “Quantifying Sampling Precision for Coal Ash Using Gy’s Discrete Model of the Fundamental Error” (Journal of Coal Quality, 1989:33–39) provides data relating the percentage of ash to the volume of a coal particle. The average percentage of ash for six volumes of coal particles was measured. The data are as follows: Volume (cm3) 0.01 0.06 0.58 2.24 15.55 276.02 Percent ash 3.32 4.05 5.69 7.06 8.17 9.36 Using the most appropriate model, predict the percent ash for particles with a volume of 48 cm3. Round answer to three decimal places. * the answer i got was of 6.260 was wrong
A vertical chemical reactor undergone a maintenance in which its internals were subjected inspection from bottom to top before catalyst loading. A site engineer (63.00 kg) was tasked to do the inspection and he stopped from time to time at each portion to inspect. A safety officer monitored the engineer’s position while watching from the top and reported his position (Refer to the photo attached. CORRECTION for data table at t=70.00 min, position=725.0 cm): Solve for: (a) Power he exerted at t = 50.00 min (b) Power he exerted at t = 65.00 min (c) Total Work he exerted throughout the inspection (d) Average Power throughout the inspection
The speed of sound traveling through the sea is a function of temperature, salinity, and pressure. It is modeled by the function C = 1449.2 + 4.67T -0.055T² +0.00029T³ + (1.34-0.01T) (S-35) + 0.016D where C is the speed of sound (in meters per second), T is the temperature (in degrees Celsius), S is the salinity (the concentration of salts in parts per thousand, which means grams of dissolved solids per 1000 grams of water), and D is the depth below the sea surface, in meters. Calculate the following (Check attached image d3) when T = 10 °C, S = 35 parts per thousand, and D = 100 m. Explain the physical meaning of these derivatives.

We are given no numbers and are instructed to generate a solution using the variables [ "R, M, g, I and H." ] Target = Find an equation that, if we could substitute numbers, would determine how long the process would take. Newton's second law and torque seem to be relevant based on how the problem is written. * Also please show drawing based on what we are calculating
