Ahorizontal steam pipe (d i = 7.8 cm, d 0 = 8.9 cm) carries saturated steam at 200.5 0 c. a 2 cm thick insulation ( k = 0.05 w/m-k) is installed to reduce heat loss to the ambient air at 25 0 c. neglecting internal convection resistance and radiation loss from the external surface, calculate the rate of heat loss per meter length of the pipe.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit.explain why the pneumatic piston stumbles when it hits an obstacle.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
