The inclined manometer in Fig contains Merriam red oil, SG = 0.827. Assume the reservoir is very large.
The jet engine in Fig P3.50 admits air at 20°C and 1 atm at (1), where A1 = 0.5 m2 and V1 = 250 m/s. The fuel-air ratio is 1:30.
The natural frequency of vibration of a mass M attached to a rod, as in Fig. depends only upon M and the stiffness EI and length L of the rod.
The liquid in Fig kerosine at 20°C. Estimate the flow rate from the tank for (a) no losses
The parallel galvanized-iron pipe system of Fig delivers water at 20°C with a total flow rate of 0.036 m3/s. If the pump is wide open and not running
The orientation of a hole can make a difference. Consider holes A and B in Fig. which are identical but reversed, for the given air properties on either side
The new AMTRAK high-speed Acela train can reach 150 mi/h, which presently it seldom does, because of the curvy coastline tracks in New England.
The Morton number Mo, used to correlate bubble-dynamics studies, is a dimensionless combination of acceleration of gravity g, viscosity µ, density ?
The main cross-cable between towers of a coastal suspension bridge is 60 cm in diameter and 90 m long. Estimate the total drag force on this cable in crosswinds
Gravel is dumped from a hopper, at a rate of 650 N/s, onto a moving belt, as in Fig. The gravel then passes off the end of the belt
Glycerin at 20°C is to be pumped through a horizontal smooth pipe at 3.1 m3/s. It is desired that
Given the incompressible flow V = 3yi + 2xj. Does this flow satisfy continuity? If so, find the stream function f(x, y) and plot a few streamlines
Given is the flow of a channel of large width b under a sluice gate, as in Fig. Assuming frictionless steady flow with negligible upstream kinetic energy
Helium at 20°C and low pressure flows past a thin flat plate 1 m long and 2 m wide. It is desired that the total friction drag of the plate be 0.5 N.
Helium at 300°C and 200 kPa, in a closed container, is cooled to a pressure of 100 kPa. Estimate
Helium, in a large tank at 100°C and 400 kPa, discharges to a receiver through a converging-diverging nozzle designed to exit at Ma = 2.5 with exit area 1.2 cm2
If 8 kg of oxygen in a closed tank at 200°C and 300 kPa is heated until the pressure rises to 400 kPa, calculate
If losses are neglected in Fig for what water level h will the flow begin to form vapor cavities at the throat of the nozzle? The response must be typed
Gasoline at 20°C flows at 105 m3/h in a 10-cm-diameter pipe. We wish to meter the flow with a thin-plate orifice and a differential pressure transducer
Gasoline at 20°C is flowing at V1 =12 m/s in a 5-cm-diameter pipe when it encounters a 1-m length of uniform radial wall suction
Gate AB has length L, width b into the paper, is hinged at B, and has negligible weight. The liquid level h remains at the top of the gate for any angle
Gate AB in Fig is 1.2 m long and 0.8 m into the paper. Neglecting atmospheric-pressure effects, compute the force F on the gate and its center of pressure
Gate AB in Fig is 5 ft wide into the paper, hinged at A, and restrained by a stop at B. Compute
Gate AB in Fig is a homogeneous mass of 180 kg, 1.2 m wide into the paper, resting on smooth bottom B. All fluids are at 20°C.
