Multiaperture photometry in V(5500 Å), r(6738 Å), and IV(10500 Å) of 52 spirals, in nearby clusters Virgo, Fornax, and Grus and farther clusters Cancer, Zw 74 - 23, and Peg I in the redshift range up to 6000 km s-1 was used to derive the total magnitudes VT, rT, and IVT. Using the corrected total magnitudes, an extensive discussion of the luminosity - H I width relation (Tully-Fisher relation) for the galaxies of these clusters is given. The absolutely calibrated relation is then used to derive distance moduli of the spiral galaxies. The resulting distances are compared with earlier determinations, if available, and good agreement is found. The best value for the global Hubble constant from farther and nearby clusters is derived as 74.3±11 km s-1Mpc-1, and an average value of 289±60 km s-1 for the infall velocity of the Local Group toward Virgo is determined.
