The cross-sectional area of the aorta A0 (the major blood vessel emerging from the heart) of normal resting person is 3 cm2, and the speed v0 of the blood through it is 30 cm/s. A typical capillary (with diameter approximately 6×10-6 m) has a flow speed v of 0,05 cm/s. How many capillaries does such a person have?

A light ray strikes a water/air surface at an angle of 46 degrees with respect to the normal. The refractive index for water is 1.33. Find the angle of refraction when the direction of the ray is from water to air.
A nozle is a deviee for incressing the velocity afa steadily lowing stream. At
the inlet toa certain nozzle. the enthalpy of the tluid passing is 3000Mkg and
the velocity is 60 ms. At the dischare end, the enthalpy is 2762 k The
nozzle is horizontal and there is negigible heat loss from it. (a) Find the velocity
al exit fron the nozzle. (b) Ir the inlet arca is 0.1 m and the specifie volume at
inlet is 0.187 m/kg. find the mass flow nie. (c) If the pecific volume at the
nozzle exit is 0.498 m'kg. ind the exit area of the nozzle.
