A capillary tube in a one-ton R22 air conditioner has a bore of 2.3 mm. Saturated liquid from the condenser enters at a temperature of 48°C and flows adiabatically through the tube until its temperature is 5°C. The friction factor is given as f = 0.32 / Re0.25. What is the length of the capillary tube? (Take intermediate sections at 40°C, 30°C, 20°C, and 10°C and the mass flow rate of the refrigerant as 0.02417 kg/s)
