Water at a temperature of 300 K enters a black (ε = 1), thin-walled tube at a flow rate of 5 kg/s. The tube passes through a furnace with walls and air at 700 K. The tube is 0.35 m in diameter and 8 m long. The convection coefficient of the air in the furnace may be assumed to be 50 W/m2K. (a) Find the convection coefficient of the water in the tube. (b) Find the exit temperature of the water

What are the two (02) benefits, which may result from a successful implementation of preventive maintenance (pm) program in an organization? (clo3)a)- lean manufacturing b)-overlapping responsibilities c)-the planner is not qualified d)-accurate contractor information e)-reduction in equipment redundancies f)-accurate stores information

Find the kinematic pressure of 160kpa. for air, r-287 j/ kg k. and hair al viscosity of air at a temperature of 50°c and an absolute (10 points) (b) find the dynamic viscosity of air at 110 °c. sutherland constant for air is 111k

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
