Tests were carried out to determine heat-transfer coefficients and effective length of tank heating coils. The former are usually calculated from a natural convection heat transter point of view, however, in such a case of crude oil heating, the values would be much increased on account of nucleate boiling of the low boiling temperature componnts. The authors experimentally clarified the boiling effects on these and obtained following empirical equations: K^^-=6.2θ_<sf>-415kcal/m^2h℃ For the latter, the authors experimentally obtained some basic data such as a frictional loss coefficient of condensing steam flow. It was found that the values of effective length calculated from the following convenient approximation formula agreed well with the experimental values: [numerical formula]
