The wye joint in Fig. P3.151 splits the pipe flow into equalamounts Q /2, which exit, as shown, a distance R 0 from theaxis. Neglect gravity and friction. Find an expression forthe torque T about the x axis required to keep the systemrotating at angular velocity V .
A hovercraft weighs M = 1500 kg and hovels without changing altitude. The exit flow exhausts to atmospheric pressure at sea-level. The flow is steady, incompressible and uniform properties can be assumed on all control surfaces. Assume air density = 122 kg/m^3.
Air, assumed frictionless, fl ows through a tube, exiting tosea-level atmosphere. Diameters at 1 and 3 are 5 cm, whileD 2 = 3 cm. What mass fl ow of air is required to suck waterup 10 cm into section 2 of Fig. P3.136?
You wish to water your garden with 100 ft of 5/8-in-diameterhose whose roughness is 0.011 in. What will be the delivery,in ft3/s, if the gage pressure at the faucet is 60 lbf/in2?If there is no nozzle (just an open hose exit), what is thethe maximum horizontal distance the exit jet will carry?
P3.5 Water at 20°C flows through a 5-in-diameter smooth pipe at a high Reynolds number, for which the velocity profile is approximated by u = U.(v/R)/8, where U, is the cen- terline velocity, R is the pipe radius, and y is the distance measured from the wall toward the centerline. If the cen- terline velocity is 25 ft/s, estimate the volume flow rate in gallons per minute.
An ideal water jet with volume flow rate of 0.05 m^ 3 / s strikes a flat plate placed normal to its path and exerts a force 1000 N Considering the density of water as 1000 kg / (m ^ 3) , find the diameter (in mm) of the water jet.
