A water jet 3 in in diameter strikes a concrete (SG =2.3)slab which rests freely on a level fl oor. If the slab is 1 ft wide into the paper, calculate the jet velocity which willjust begin to tip the slab over.

P6.13 In a pipeline that connects a production oilfield to a tanker terminal, oil having density 953 kg/m and viscosity 0.287 kg/(m · s) flows through a 1.2 m diameter pipeline at 9.5 km/h. What is the Reynolds number? Is the flow laminar or turbulent?

For a high-fl ow site with a head of 45 ft, it is desired to designa single 7-ft-diameter turbine that develops 4000 bhp at aspeed of 360 r/min and 88-percent effi ciency. It is decidedfi rst to test a geometrically similar model of diameter 1 ft,running at 1180 r/min. (a) What likely type of turbine is inthe prototype? What are the appropriate (b) head and(c) fl ow rate for the model test? (d ) Estimate the powerexpected to be delivered by the model turbine.

SAE 50W oil at 20 °C flows from one tank to anotherthrough a tube 160 cm long and 5 cm in diameter. Estimatethe flow rate in m3/hr if z1 = 2 m and z2= 0.8 m.

Gasoline at 20°C fl ows at 3 m3/h in a 6-cm-diameter pipe.A 4-cm-diameter thin-plate orifi ce with corner taps isinstalled. Estimate the measured pressure drop, in Pa.

SAE 10 oil at 20°C fl ows at an average velocity of 2 m/sbetween two smooth parallel horizontal plates 3 cm apart.Estimate (a) the centerline velocity, (b) the head loss permeter, and (c) the pressure drop per meter.

Ethylene glycol at 20°C flows through 80 m of cast ironpipe of diameter 6 cm. The measured pressure drop is250 kPa. Neglect minor losses. Using a noniterative formulation,estimate the flow rate in m3/h.
