| Abstract: | In view of the problems in the calculation of turbulent friction coefficient of stainless steel round tube,the resistance performance of stainless steel round tube was measured in the range of Reynolds number from(1~15)×104,and the turbulent friction coefficient was calculated and analyzed.On this basis,the empirical formula for calculating the turbulent friction coefficient of stainless steel round tubewas put forward,and compared with the commonly used formula for calculating the turbulent friction coefficient of smooth tube.The results show that the calculated value of the empirical formula is basically consistent with the measured value,and the average error is 0.606%and the maximum error is 1.256%. |
