Dimensionless equations to calculate capillary tubes
Annotation
The paper considers a sequence of getting empirical dependences for calculating capillary tubes. It is proposed to realize regression analysis of data for every refrigerant throttled separately, roughness of tubes being allowed for without fail. Exponential function with six dimensionless variables is chosen for the correlation. Statistical estimates of the exponents are obtained by linear regression computer program, which confirmed the adequacy of the model. Numerical values of the exponents in the equations for calculating the length of the tube and its capacity with throttling six modern refrigerants are listed in two tables.
