The diameter of the inlet part is 7 cm and the diameter of the throat part is 4 cm. Water flows through the venturimeter. The pressure at the inlet is measured as 430 kPa. If the volumetric flow of water is 33 L/s, calculate the pressure in the throat (kPa) according to Bernoulli's principles, ignoring the effects of friction (Density of water is 1 kg/liter).
