A pump delivers water at 20°C between a reservoir and a water tank 24 m higher. The suction side consists of a strainer (ks = 2.

5), three 90° bends (R/D = 4), and 50 m of ductile-iron pipe, 35 cm in diameter. The discharge side includes a 155-m-long, ductile iron pipe, 20 cm in diameter, and a gate valve. Assume the friction factor throughout the pipeline is 0.018, the NPSH required is 5m, and the design discharge is 300 L/s. Determine the allowable elevation difference between the pump and the reservoir water surface to avoid cavitation. Assume the strainer coefficient includes the entrance loss coefficient.

when removing the pistons and rods assemblies from a cylinder block technician a positions the throw of the crankshaft at the to
defon

Answer: Technician A

Reason: Piston and rod are connected with crank shaft and connecting rod. Smaller end of connecting rod is connected with piston and bigger end is connected with crankshaft.  

<u>Explanation: </u>

When removing the piston and rod assemblies from a cylinder block: The technician with correct approach. So to remove piston from cylinder technician must throw crankshaft first and the remove connecting rod by losing nuts and caps...So technician A is in right way. Technician B using hammer to remove piston from the rod not possible because connecting rod and piston connected by nuts and caps can’t be separate by hammer.  

Technician A positions the throw of the crankshaft at the top of its stroke and removes the connecting rod nuts and cap.

Technician B covers the rod bolts with hammers and pushes the piston and rod assembly out with the wooden hammer handle or wooden drift and supports the piston as it comes out of the cylinder.

Stainless steel ball bearings (rho = 8085 kg/m3 and cp = 0.480 kJ/kg·°C) having a diameter of 1.2 cm are to be quenched in water
sveticcg [70]

Answer:

\dot Q = -2.341\,kJ

Explanation:

The rate of heat transfer from the balls to the air is:

\dot Q = \left[(800\,\frac{1}{min} )\cdot (\frac{1\,min}{60\,s} )\cdot(8085\,\frac{kg}{m^{3}})\cdot (\frac{4}{3}\pi )\cdot (6\times 10^{-3}\,m)^{3}\right]\cdot (0.480\,\frac{kJ}{kg\cdot ^{\textdegree}C} )\cdot (850\,^{\textdegree}C-900\,^{\textdegree}C)\dot Q = -2.341\,kJ
