Problem 9.56

A long, uninsulated steam line with a diameter of 89 mm and a surface emissivity of 0.8 transports steam at 200C and is exposed to atmospheric air and large surroundings at an equivalent temperature of 20C. (a) Calculate the heat loss per unit length for a calm day. (b) Calculate the heat loss on a breezy day when the wind speed is 8 m/s. (c) For the conditions of part (a), calculate the heat loss with a 20-mm-thick layer of insulation (k 0.08 W/mK). Would the heat loss change signifi- cantly with an appreciable wind speed?

IEA Week 4 Notes LECTURES 13 & 14 Forces on a rigid body may cause it to either (TRANSLATE) or (ROTATE) For a rigid body to be in equilibrium, the net force and the net moment at any point must be ZERO. **Internal forces can be neglected, as they do not add to net force or net moment Center of Gravity The center of gravity is the point on a rigid body at which we can say all of the mass of this object exists. 1. Draw a Free body diagram of a rigid object 2. Draw all external forces and couple moments 3. Label all loads and dimensions with magnitudes and directions RULES ­  If a support prevents translation, then a force is developed on the body in the opposite direction  If rotation is prevented, a couple moment is exert
