Asteel pipe (k=45.0 w/m-k) having a 5.0 cm o. d. is covered with a 4.2 cm thick layer of magnesia (k=0.07 w/m-k) which is in turn covered with a 2.4 cm layer of fiberglass insulation ((k= 0.048 w/m-k). the pipe wall outside temperature is 370k and the outside surface temperature of the fiber galss is 305k. what is the interfacial temperature between the magnesia and the fiberglass?

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

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.

Ifa component is made of two or more materials with different modulus of elasticity (e), it is called a composite member and we calculate the factor·n". mention the formula for calculating n". also, ifn> 1, explain what will happen to the 1. transformed.gi) ifn 1, what will happen to the material when transformed material when
