A Pitot-static probe connected to a water manometer is used to measure the velocity of air. If the deflection (the vertical distance between the fluid levels in the two arms) is 7.3 cm, determine the air velocity. Take the density of air to be 1.25 kg/m3.
Single degree of freedom vibration problems with forcing functions, Need help with this Undergraduate problem where two dampers are in series.
find the natural frequency of a pendulum for small angle deflections when the mass of the rod/string is not negligible. (Mass of rod = m, mass of ball = M.
find the total heat loss per m length of the steam line. Find also the temperature at the interface of steam and insulation.
Model the earth as a sphere with a diameter of 8,000 miles. Using 14.7 psia as the average pressure at the earth's surface and ignoring variation in g with altitude, estimate the weight of the earth's atmosphere in lbf, and its mass in lbm.
a beam consists of three planks connected as shown by 3/8 in diameter bolts spaced every 12in.along the longitudinal axis of the beam.knowing that the beam is subjected to a 2500lb vertical shear, determine the average shearing stress in the bolts..
Twenty-five samples of steel beam were chosen and tested for Young's Modulus. Eight had a modulus of E = 30 x 10^6 psi. Two had a modulus of E = 29 x 10^6 psi. Fifteen had a modulus of E = 30. x 1-^6 psi.
A luge and its rider, with a total mass of 98 kg, emerge from a downhill track onto a horizontal straight track with an initial speed of 39 m/s.
Steam at 1000kPa and 300deg C expands to a pressure of 150kPa in a cylinder. If PV = constant during the process, calculate W, Q and delta S for the process.
A square 3m x 3m gate is located in the 45* sloping side of a dam. Some measurements indicate that the resultant force of the water on the gate is 500kN.(a)Determine the preassure at the bottom of the gate.(b)Show on a sketch where this force acts..
the snowmobile is traveling at 10m/s when it leaves the embankment at A.determine the speed at which it strikes the ground at B and its maximum acceleration along the trajectory AB.
A steel alloy to be used for a spring application must have a modulus of resilience of at least 2.07 MPa (300 psi). What must be its minimum yield strength?
what will be the final temperature in the tank? how much work will be accomplished over the course of the entire process?
