Question Solved1 Answer (17\%) Problem 1: A Venturi meter is a horizontal tube with a wide section and a narrow section, each of which is attached to a vertical tube. The pressure difference between the vertical tubes, caused by fluid moving through the horizontal tube, is measured with a U-tube manometer. For the device shown, assume the ratio between the diameters is \( 4.26 \). (17\%) Problem 1: A Venturi meter is a horizontal tube with a wide section and a narrow section, each of which is attached to a vertical tube. The pressure difference between the vertical tubes, caused by fluid moving through the horizontal tube, is measured with a U-tube manometer. For the device shown, assume the ratio between the diameters is 4.26. Additionally assume that the fluid in the U-tube manometer is mercury with a density of 13,600 kg/m3. Suppose that the fluid moving through the horizontal section is oil with a density of 873 kg/m3, and the difference between the mereury levels on the left-hand and right-hand sides of the manometer is 1.81 cm.

Two horizontal wires are joined end to end, each with a diameter of 2.000 mm. The two joined wires are connected to fixed points a total distance of 4.00000 m apart. When both wires are at a temperature of 47.0°C, each wire has an unstretched length of 2.00000 m, and the tension in each is negligible. The first wire is made of copper and extends from x = -2.00000 m to x = 0, and the second is made of aluminum and extends from x = 0 to x = 2.00000 m. The temperature of both wires is then lowered to 16.0°C, and the wires stay joined together as they cool. The copper wire is composed of an alloy that has an average coefficient of linear expansion of 1.70 x 10-5(°C) -1 and a Young's modulus of 1.10 x 10' N/m2. The aluminum wire is composed of an alloy that has an average coefficient of linear expansion of 2.40 x 10-5C) and a Young's modulus of 7.00 X 100 N/m? (Due to the nature of this problem, do not use rounded intermediate values in your calculations-Including answers submitted in WebAssign.) (a) At the final, lower temperature, what is the x-coordinate (in m) of the junction between the wires? (No Response) (b) At the final, lower temperature, what is the tension (in N) in the wire? (No Response) N

A Tim Horton's has recently opened up in Edmonton. It is observed that, on any given morning, the time it takes for a car to be served after ordering in the drive-thru follows a normal distribution with = 8 minutes and a = 2.5 minutes. (a) What is the probability that it takes less than 5.5 minutes for a randomly selected car to be served after ordering? (Round your answer to four decimal places, if needed.) (b) What is the probability that it takes more than 70 minutes for a randomly selected car to be served after ordering? (Round your answer to four decimal places, if needed.) Find the area under the standard normal distribution represented by each probability. (Round your answers to 4 decimal places.) (a) PIZ < -0.56) (b) P(Z > 1.07): (c) P(0.51 < Z < 1.6): (d) PIZ = 1,87): Check

Q.17: Heat in the amount of 7.5 kJ is added to a closed system while its internal energy decreases by 12 kJ. How much energy is transferred as work? For a process causing the same change of state but for which the work is zero, how much heat is transferred?

Blue Spruce Corp. has decided to expand its operations. The bookkeeper recently completed the following statement of financial position in order to obtain additional funds for expansion:obligation is considered a long-term liability.

(15 points): Consider (again) the complex function G: C+C defined by 8 +2 G(8) 32 +63 + 18 (a) By hand, draw a pole-zero map of G (i.e., in the complex plane, draw a "o" to indicate points where G evaluates to zero and an "x" to indicate points where the magnitude of G tends to infinity).

The problem is Customers arrive at a tool crib according to a Poisson process of rate $\lambda = 5$ per hour. There is a single tool crib employee, and the individual service times are exponentially distributed with a mean service time of 10 minutes. In the long run, what is the probability that two or more workers are at the tool crib being served or waiting to be served? It is given that $\lambda = 5$, and I believe that $\mu = 6$ customers per hour. Then, I think the answer is $$1-\frac{1}{6}-\frac{1}{6}\left(\frac{5}{6}\right)-\frac{1}{6}\left(\frac{5}{6}\right)^2 = \frac{125}{216}.$$ However, the answer in the back is $\frac{25}{36}$. I was wondering what I did wrong. Or is the answer in the back wrong? Thanks.
