The period of oscillation T of a water surface wave is assumed to be a function of density ?, wavelength ?, depth h, gravity g, and surface tension Y
The period T of vibration of a beam is a function of its length L, area moment of inertia I, modulus of elasticity E, density ?, and Poisson's ratio s
The pipe bend of Fig. has D1 = 27 cm and D2 = 13 cm. When water at 20°C flows through the pipe at 4000 gal/ min, p1 = 194 kPa (gage). Compute the torque
The pump of Fig is used to deliver 0.7 m3/s of methanol at 20°C through 95 m of cast-iron pipe. What is the proper pipe diameter?
The pump in Fig draws gasoline at 20°C from a reservoir. Pumps are in big trouble if the liquid vaporizes (cavitates) before it enters the pump.
The pump in Fig creates a 20°C water jet oriented to travel a maximum horizontal distance. System friction head losses are 6.5 m.
The pressure in the air gap is 8000 Pa gage.The tank is cylindrical. Calculate the net hydrostatic force
The power P generated by a certain windmill design depends upon its diameter D, the air density ?, the wind velocity V, the rotation rate O
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
