A copper tube (length, 3.0 m; inner diameter, 1.500 cm; outer diameter, 1.700 cm) passes through a vat of rapidly circulating water maintained at 20 °C. Live steam at 100 °C passes through the tube. (a) What is the heat flow rate from the steam into the vat? (b) How much steam is condensed each minute? For copper, kT = 1.0 cal/s·cm·°C. |
