A Pitot-static probe connected to a water manometer is used to measure the velocity of air. If the de?ection (thevertical distance between the ?uid levels in the two arms) is 7.3 cm, determine the air velocity. Take the density of air to be 1.25 kg/m3.
A spherical balloon inflated sos that the volume is increasing at the rate of cubic meter/min. At what rate is the diameter increasing when the diameter is 12 m?
Construct the homogeneous solution in terms of four constant that could be determined from initial conditions and show the equations of motion
What are the percentages of the total heat absorption taking place in the economizer, boiler drum and the superheater, respectively? Assume cp of air and water as 1.005 kJ/kg K and 4.2 kJ/kg K, respectively.
the motion of the slender 10kg rod AB is guided by collars of negligible mass that slide freely on the vertical and horizontal rods. knowing that the bar is released from rest when θ=30, determine the velocity of the collars A and B when θ = 60.
Determine the acceleration of the cabinet when sA = 40 ft. Note that when sB = 0, sA = 0 (points A and B are coincident).
A pitching wedge a golfer is using gives the ball a initial angle of 50 degrees, what range of velocities (Vo) will cause the ball to land within 3 ft of the hole?
the collar has a mass of 20kg and is supported on the smooth vertical rod. the attarched springsare undeformed when d=0.5m determine the speed of collar after the applied force F=100N causes it to be displaced so that d=0.3m when d=0.5m, the colla..
Determine metal removal rate, etching time, and required dimensions of the opening in the cut and peel maskant required to achieve the desired pocket size on the part.
As shown, a 150 lb bungee jumper wants to jump from the top of a 630 ft high bridge and be able to just touch the water below. Given that the bungee cord has a spring constant of 108 lb/ft, what should the bungee cord's relaxed length, l, be for t..
