Final Answer:
The statement given "50% part (a) calculate the pressure drop due to the bernoulli effect as water enters the nozzle from the hose at the rate of 40.0 l/s. take 1.00 × 103 kg/m3 for the density of the water." is true because the pressure drop due to the Bernoulli effect is true because the speed of water increases as it enters the nozzle from the hose, causing a decrease in pressure. Option A is answer.
Step-by-step explanation:
The Bernoulli effect states that as the speed of a fluid increases, its pressure decreases. In this case, as water enters the nozzle from the hose, its speed increases due to the decrease in the cross-sectional area of the nozzle. This increase in speed leads to a decrease in pressure, which is known as the pressure drop due to the Bernoulli effect.
The pressure drop due to the Bernoulli effect occurs as the speed of water increases when entering the nozzle from the hose. This decrease in pressure is caused by the reduction in cross-sectional area at the nozzle.
Option A is answer.
