It is proposed that a model study be carried out on a proposal low-speed airfoil that is to fly at low altitudes at a speed of 50 m/s. If a 1:10 scale model is to be constructed, what velocity should be used in a wind tunnel? Comment as to the advisability of such a test. Would it be more advisable to perform the test in a 20?C water channel? If a water channel study were undertaken, calculate the drag ratio between the model and prototype.

Consider the low-speed airflow over the NACA 0012 airfoil at low angles of attack. The Reynolds number based on the chord is roughly Rec = 2.88 × 10^6. This flow can reasonably be modeled as incompressible and inviscid. The initial input value for your simulations is provided on the bottom of this assignment. Your need to generate a report to give background introduction, and address the following issues: (inlet Velocity: 1.5 Attack angle: 5) 1. Incompressible, Inviscid Model: Explain why...

A study was carried out to determine whether the resistance of a control circuit in a machine is lower when the machine motor is running. To investigate this question, some of the control circuits were tested as follows. Their resistance was measured while the machine motor was not running and then again while the motor was running for a certain period of time. The values found are listed in ‘Dataset’, with kilo-Ohms as the unit of measurement. Answer the following...

An experiment was carried out to study the effect of the percentage of ammonium (Factor A) and the stir rate (Factor B) on the density of the powder produced. The results are in the accompanying table. Complete parts (a) through (e). At the 0.01 level of significance is there an interaction between the percentage of ammonium and the stir rate? - Stir_Rate - Percent_of_Ammonium 100 150 2% 10.83 8.49 2% 14.64 6.84 2% 18.46 9.05 2% 15.86 9.54 30% 12.29 ...

A study was carried out to determine the putting accuracy of golf players on uphill and downhill putts from five feet. In a sample of 100 uphill putts, 90 putts were successful. In a sample of 80 downhill putts, the number of successful putts was 60. Assume α=.05 Is there evidence that the proportion of uphill putts successfully made is larger than downhill putts? Suppose p1=0.95 and p2=0.7. What is the sample size required to have a power of test...

Use R studio to answer the following. A study was carried out to investigate the variation of rainbow trout weights in a certain creek. The weights (in kilograms) of 10 randomly selected fish are listed below: 0.78, 0.45, 0.35, 0.76, 0.57, 0.42, 0.33, 0.68, 0.66, 0.42 Assume that the population is approximately normally distributed. Hint: make a vector to enter the weight data into R, e.g.: > wt = c(0.78, ..., 0.42) Find the 90% confidence interval for the unknown population...

A study was carried out to determine the number of women using folic acid supplements in early pregnancy. All women attending a public or private clinic in Ohio were invited to participate and 28 women accepted. Based on previous studies, we know that typically 62% of pregnant women take folic acid supplements during early pregnancy. a) What is the probability that exactly 25 women take a folic acid supplement during early pregnancy? (Use formula/show work, NOT binompdf or binomcdf.) b)...
