Compare the frictional pressure drop due to the vapor flow to that due to the liquid flow through the wick for a heat pipe using ammonia as the working fluid. Assume that the ratio of dynamic viscosities of ammonia is µI/µV = 3.0, the inside diameter of the wick is 2 cm and the annular area of the wick is 0.65 cm^2. The wick is phosphor-bronze.
