What is the Young’s modulus in GPa
Pressure distribution measurements are made on a two-dimensional wing model placed in a wind tunnel. The difference between the static pressure sockets on the surface and the static pressure of the free stream is measured. 30 data is taken at each measurement point. The average of the values measured from one of the sockets near the trailing edge was calculated as 2.30 Pa, and the standard deviation was calculated as 2.65 Pa. After applying the Chauvenet criterion to these measurement values, it was decided to eliminate 3 measurements and the new mean value was found to be 2.18 Pa and the standard deviation was 2.42. It was verified that the unexcluded data fit the normal distribution curve. Data above how many Pa and below how many Pa were eliminated? Estimate how many data have negative value (?<0) after elimination.

A flexible pavement has a 4-inch sand-mix asphalt wearing surface, 10-inch soil cement base, and a 10- inch crushed stone subbase. It is designed to withstand 400 20-kip single-axle loads and 900 35-kip tandem-axle loads per day. The subgrade CBR is 8, the overall standard deviation is 0.45, the initial PSI is 4.2, and the final PSI is 2.5. What is the probability that this pavement will have a PSI above 2.5 after 25 years?

Q1. Honey is a very widely used ingredient in cooking all around the world. Many commercial honey manufacturers heat treat honey to remove harmful bacteria that may be present. The density and viscosity of the honey varies with temperature, as shown in table 1.

A particular processing facility heats and sterilises 500 kg of unprocessed honey every 30 minutes. The unpro- cessed honey is stored in large vats, then pumped though pipes into heating units before being pumped through another pipe to be bottled. The pipe carrying the honey from a storage container, which is 11 m tall, to a heating unit is 5 m long and has a diameter of 10 cm. Prior to being heated the honey is kept at 25°C. (a) What is the pressure difference between the top and bottom of a storage vat when it is full? (b) What is the volume flow…
Two soft drink machines dispense liquids of 10 ounces, on the average. The question is whether the two machines are equally consistent in the dispensing of the liquid. To answer this question, a sample of size 10 was obtained from each machine and the sample standard deviations were computed to be s1 = 1.87 ounces and s2 = 1.25 ounces. Perform the appropriate test of hypothesis using α = 0.05
