Explanation Write the relation between the velocity at inlet and velocity at outlet using the continuity equation. Q = A 1 V 1 = A 2 V 2 (I) Here, the area of the outlet is A 2 , the velocity of the inlet is V 1 , the velocity of the outlet is V 2 , the diameter of the pipe is D 1 , and discharge is Q . Write the expression to determine the 9 holes in the grill hole area ( A 2 ) . A 2 = 9 × π 4 D 2 2 (II) Here, the diameter of the hole is D 2 . Write the Bernoulli's equation for the inlet and outlet streams for points (1) and (2). p 1 γ + V 1 2 2 g + Z 1 = p 2 γ + V 2 2 2 g + Z 2 (III) Here, inlet pressure is p 1 , outlet pressure is p 2 , specific weight of air is γ , acceleration due to gravity is g , the initial datum is Z 1 , and the final datum is Z 2 . Conclusion: Substitute 0 for V 1 , 0 for Z 1 and Z 2 , ρ g for γ , and 0 for p 1 in Equation (III). 0 γ + 0 2 g + 0 = p 2 ρ g + V 2 2 2 g + 0 p 2 = − ρ × V 2 2 2 g (IV) Substitute 0

A 3-in.-radius drum is rigidly attached to a 5-in.-radius drum as shown. One of the drums rolls without sliding on the surface shown, and a cord is wound around the other drum. Knowing that at the instant shown. point A has a velocity of 4.875 in./sin./s and an acceleration of 15.50 in./s2in./s2 , both directed to the right, determine the accelerations of points A, B, and C of the drums. The cord is wound around the 3 inch radius drum. Point B is at the bottom of the 5 inch radius drum. Point A is at the bottom of the 3 inch radius drum. Point C is on the right edge of the 5 inch radius drum. The accelerations of point B is ______ in./s2 The accelerations of point A is ______ in./s2 _____⦨ °. The accelerations of point C is _______ in./s2 ____ ⦪ °.

The average heat transfer coefficent for airflow over an odd shaped body is to be determined by mass transfer measurements and using the Chilton-Colburn analogy btwn heat and mass transfer. The experiemnt is conducted by blowing dry air at 1 atm at a free-stream velocity of 2 m/s over a body covered with a layer of naphthalene. The surface area of the body is .75 m^2, and it is observed that 100 g of maphthalene has sublimated in 45 min. During the experiemnt, both the body and the air were kep at 25oC, at which the vapor pressure and mass diffusivity of naphthalene are 11 Pa and Dab=0.61*10^-5 m^2/s respectively. Determine the heat transfer coefficent under the same flow conditions over the same geometry.
