Water flows through a cast steel pipe (k = 50 W m. K, ε = 0.8) with an outer diameter of 104mm and 2 mm wall thickness. Calculate the heat loss (convection and radiation) per meter length of uninsulated pipe when the water temperature is 90 oC, the outside air temperature is -10 oC, the water side heat transfer coefficient is 300 W m2.K and theoutside heat transfer coefficient is 20 W/m^2K.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
