DETERMINATION OF THE INITIAL VELOCITY AND DURATION OF MOTION OF A FLUID IN CAPILLARIESV. Z. Kanchukoev, B. S. Karamurzov, V. A. Sozaev, and V. V. Chernov UDC 541.532.264 The method of determination of the initial velocity and duration of motion of a fluid in capillaries which is based on reduction of the boundary-value problem under study to Cauchy problems for systems of ordinary differential equations is presented.
