### Problem 3: Air Flow in a Circular Duct with Conical Centerbody**Description:** Air is flowing down a circular duct as shown in the figure. At station 1, the velocity is \( V_1 \) and the duct diameter is \( D_1 \). The duct gradually enlarges to station 2, where the air exits to the atmosphere, and the diameter is \( D_2 \). A conical centerbody with a cone angle \( \theta = 30^\circ \) is inserted into the duct exit. The diameter of the cone base is \( d \). You may assume that the velocity is low enough that \( \rho \) (air density) is constant.**Figure Explanation:**- The diagram shows a circular duct with a control surface enclosing the air flow.- The air enters at station 1 with velocity \( V_1 \) and diameter \( D_1 \).- The duct then expands, and air exits at station 2 with velocity \( V_2 \) and diameter \( D_2 \).- The conical centerbody located at the exit has a cone angle \( \theta \) of \( 30^\circ \) and a base diameter \( d \).- The force \( F \) is acting horizontally to hold the cone in place.**Figure:**- The diagram visually represents the described scenario with a clear illustration of velocities, diameters at different positions, and the conical centerbody.**Given Data:**- \( V_1 \) = 20 m/s- \( D_1 \) = 30 cm- \( D_2 \) = 60 cm- \( d \) = 58 cm- Air density \( \rho \) = 1.225 kg/m³ (standard conditions)#### Questions:(a) **Find an expression for the gauge pressure at station 1 in terms of \( V_1, D_1, D_2, d, \theta, \) and \( \rho \). What assumptions do you have to make to solve this problem?**(b) **What is the force, \( F \), required to hold the cone in place? You may ignore the weight of the cone.**---

Find an expression for the gauge pressure at station 1 in terms of V₁, D₁, D2, d, e, and p. What assumptions do you have to make to solve this problem? What is the force, F, required to hold the cone in place? You may ignore the weight of the cone. Use the following values: V₁ = 20 m/s, D₁ = 30 cm, D₂ = 60 cm, and d = 58 cm. You may assume that the air density is at standard conditions, p = 1.225 kg/m³.

An easy experiment to estimate the density of a body is to weigh it in air and water. Consider a body of unknown density and volume. You weighed it in air, finding a value of 100 N. Then, using a special scale imported from the United States, you weighed the object submerged in water, finding a value of 5.6 lbf. Based on these results, find the density and volume of the object. Remember that the scale measures the result of the balance of forces on the body (or the sum of the forces). Show this balance of forces (or force diagram) on the body during your solving. Express the result in units of the International System and the American System of Engineering, and show any unit conversion calculations using the conversion factor. Consider the densities of water and air equal to 1000 kg/m3 and 1.18 kg/m3, respectively.
Hi, I think you forgot to divide the answer by 2 as indicated in your initial formula. Moreover, I tried solving the problem using the formula I attached as image here and I got a positive value of the answer you came up with. What answer would be the right one? Also, please explain the cause and effects of having that certain value of theoretical pressure drop in the problem. Thank you so much!

A well is 3500 meters deep and 3100 meters vertically deep. It is filled with two drilling fluids, the first with a density of 10.5 lb/gal located up to 1000 meters and the rest of the well is filled to the bottom with fluid with a density of 12 lb/gal. During the operation, a wellhead pressure equivalent to 320 psi was recorded. With these data in hand, the pressures occurred at the bottom of the well and the equivalent density of the bottom of the well in lb/gal are, respectively: The. 6389 psi/12.12 lbs/gal 6429 psi/ 12.1 lbs/gal 5959 psl/13.2 lbs/gal 6220 psi/11.9 lbs/gal E 20:13 + 130% =
