8. Explain the working principle of a Venturi meter State three applications of Venturi meter Mention two applications of Bernoulli's principle. The pulmonary artery, which connects the heart to the lungs has an inner radius of 2.6 mm and is 8.5 cm long. If the pressure drop between the heart and the lungs is 3x10³ Nm-², what is the average speed of blood in the pulmonary artery. Determine volume flow rate of blood. Assume body temperature of 37° C, and the coefficient of viscosity of blood = 4.0x10-3Nm -2 at 37°C.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
