Task id13403
A gap with a width of d = 10-4 cm and a length of l = 5 cm has formed in the bottom of a vessel with liquid helium. The thickness of the bottom of the vessel is d = 0.5 mm. Find the maximum velocity of helium in the slot vmax and the total liquid flow rate dM/dt if the height of the helium column above the bottom of the vessel is h = 20 cm. The density and viscosity of helium are p = 0.15 g/cm3, h = 3.2•10-5 g/(cm•s). (Flow rate is the mass of liquid flowing through a slit in one second.)
