Người ta sử dụng hệ thống cô đặc 3 nồi xuôi chiều tuần hoàn tự nhiên để cô đặc dung dịch đường có suất lượng 10 tấn/giờ từ nồng độ 18%(KL) lên 50%(KL). Nhập liệu ở nhiệt độ sôi. Áp suất hơi đốt ở nồi đầu là 3ati. Chiều cao ống truyền nhiệt là 3m. Áp suất chân không trong thiết bị ngưng tụ baromet là 0,84at.
a. Tính cân bằng vật chất
b. Tính cân bằng nhiệt lượng
c. Tính nhiệt độ hơi nước bão hòa cần thiết
d. Tính lượng hơi đốt cần thiết cấp cho hệ thống cô đặc

Along 8-cm diameter steam pipe whose external surface temperature is 900c connects two buildings. the pipe is exposed to ambient air at 70c with a wind speed of 50 km/hr blowing across the pipe. determine the heat loss from the pipe per unit length. (b) air at 500c enters a section of a rectangular duct (15 cm x 20 cm) at an average velocity of 7 m/s. if the walls of the duct are maintained at 100c. a) the length of the tube for an exit temperature of the air to be 40 0c. b)the rate of heat transfer from the air. c) the fan power needed to overcome the pressure drop in this section of the duct.
