The crux of the problem asks you to compute the elastic modulus of a pancake--for this we give you numbers that we got from our own measurements of the pancakes. The last question asks you to hypothesize about which ingredients are playing the role of flour in the gluten free recipes. If you find this topic interesting, you may want to consider exploring something like this for your final project, and design an experiment to understand the difference between the normal and gluten free recipe and try to manipulate the gluten free recipe to better resemble the normal pancakes.If you choose to make the two recipes and compare them in your own kitchen, make sure you use exactly the same protocol for each recipe: In our trials, we made the batter, and then cooked on a skillet, using 1/4 cup of batter per pancake, and flipped when the edges were firm and golden, about 4-5 minutes on each side.Consider a stack of six pancakes. Each pancake is made of 1/4 cup (approximately 60 mL) of batter,…

Suppose you are given data in SI units (mass in kg and length i  meters)and because there is such a large number of calculating to be made you prefer to use the data as given rather converting them all. Modify the given equation so that the pressure drop calculated would be in bf/ft2 but the other terms would be in si units

Chapter 7, Problem 63, there is an 'h' value that is solved when expressing half the width of the Rankine Oval that I am not quite understanding the process by which the value is solved for. Could you break down the process by which h=0.02423 m? It's been a while since I was last in school, so the mathematical method by which 'h' was solved is a little unclear to me.

from this video: https://youtu.be/UvMmfacVA24 COntext: From the first setup where there is no newspaper present, the ruler fell down easily as I do a quick karate chop. In the second setup where there a sheet of newspaper over the ruler that is on the table, the ruler broke as I karate chop the ruler because of the atmospheric pressure present below and above the paper. When the paper was suddenly forced up by the ruler. A low pressure forms under the paper like a vacuum sucking the paper down and resulted in the ruler cutting in half. Explain the difference in the results of the setups using concepts about fluids. Use schematic diagrams/FBD if needed.

1. A special-purpose piece of laboratory glassware, called a pyncnometer; is used to measureLiquid densities. It has a volume of 25 cc, and a mass of 17 .24 g when it is full of air. Whenfilled with a liquid of unknown density, its mass = 45.00 g. What is the density of this liquid?How large an error do we make if we ignore the mass of the air that was in it when we weighed itand found m = 17.24 g?

Homework Parts A and Part B Problem statement: A simply supported beam of diameter D, length L, and modulus of elasticity E is subjected to a fluid crossflow of velocity V, density p, and viscosity µ. Its center deflection ô is assumed to be a function of all these variables. Part A- Rewrite this proposed function in dimensionless form. (Hint: Take L, p, and V as repeating variables.) Part B- Suppose it is known that 8 is independent of µ, inversely proportional to E, and dependent only upon pV², not p and separately. Simplify the dimensionless function accordingly.

flued mechanics  The inclined manometer at Fluid Dynamic laboratory at E5 has broken. You are tasked to design a new inclined manometer as shown in Figure 1.   The design task is to decide what is the proper manometric fluid to be used, angle of inclination (θ), and the length of the vertical (L1) and inclined (L2) leg of the manometer. Since the manometer is mainly used together with Pitot-Static tube to measure air velocity it needs to be sensitive to a small pressure difference which in the range of 5 to 50 Pa. It should be notice that the manometer should fit in a compartment which has 15 cm-height and 80 cm-length. The inclination angle should be at least 5°. The temperature in the lab is around 27 °C to 37 °C. The manometric fluid should fulfil the following criteria: The fluid should have a low vapour pressure (A liquid with high vapour pressure would be less sensitive to changes in pressure) The fluid should have low surface tension to avoid the capillary rise. High boiling…

4. A barometer (see Figure 2) is used to measure atmospheric pressure and is filled with a high- density fluid. In the past, mercury was used, but because of its toxic properties it has been replaced with a variety of other fluids. The pressure, P, measured by a barometer is the height of the fluid column, h, times the density of the liquid, p, times the acceleration due to gravity, g, or P P = h X p x g. This equation could be solved for the height: h = PE Find the height to which the liquid column will rise for pressures from 0 to 100 kPa for two different barometers. Assume that the first uses mercury, with a density of 13.56 g/cm2 (13,560 kg/m2) and the second uses water, with a density of 1.0 g/cm³ (1000 kg/m³ ). The acceleration due to gravity is 9.81 m/s2. Before you start calculating, be sure to check the units in this calculation. The metric measurement of pressure is a pascal (Pa), equal to 1 kg/m s. A kPa is 1000 times as big as a Pa. Your answer should be a two-dimensional…
