1) A water fountain is to be installed at a remote location by attaching a cast iron pipe directly to a water main through which water is flowing. The entrance to the pipe is sharp-edged 15m (K-0.5), and the 15m long piping system involves three 90 bends without vanes (K1.1), a fully open gate valve (K.-0.2), and a fully open angle valve (K-5). If the diameter of the pipe is 2 em and the system is to...

67. Find the rim thickness for a cast iron flywheel with a width of 200 mm, a mean diameter f 1.2 in a normal operating speed of 300 rpm, a coefficient fluctuation of 0.05 and which is capable of hanging 3000 N-m of kinetic energy. Assume that the hub and arms represent 10% of the rim weight and the specific weight of cast iron is 7200...

A 5-cm-diameter shaft rotates at 4500 rpm in a 15-cm long, 8-cm-outer-diameter cast iron bearing (k =70 W/m.K) with a uniform clearance of 0.6 mm filled wwith tubricating oil (u 0.03 N.s/m2 and k 0.14 W/m.K). The bearing is cooled externally by a liquid, and its outer surface is maintained at 40°C. Disregarding heat conduction through the shaft and assuming one- dimensional heat transfer, determine (a) the rate of heat transfer to the coolant, (b) the sutacs temperature of the...

A 3-m-diameter tank is initially filled with water 2 m above the center of a sharp-edged 10-cm-diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere through a 100-m-long pipe. The friction coefficient of the pipe is taken to be 0.015 and the effect of the kinetic energy correction factor can be neglected. In order to drain the tank faster, a pump is installed near the tank exit. Water tank Pump Required...

6. (10 pts) A patient with a broken leg was placed in traction using the system shown below at left. Once the cast is off of the foot, the system can be modeled as shown at right where m is the mass of the cast. In a most unfortunate incident, the cast slips off of the patient's foot and is flung by the traction system. In this problem, model...
