The quantity H, heat absorbed per hour, is found readily by the formula Where H =W (t^ —ti)c H = weight of oil heated per hour in poundsti = initial temperature of oil, degree := final temperature of oil, degrees = specific heat of oil, ^= The quantity K, coefficient of heat transfer, varieswith the difference in temperature between thesteam and the oil, and with the velocity of oil inpassing throu
