Answer :
Final answer:
To find the average friction loss in the 2 1/2in hose, calculate the pressure drop due to height change and diameter widening.
Explanation:
To calculate the average friction loss PSI in the 2 1/2-inch hose, several factors need consideration. First, determine the pressure drop due to the height change of 2.50 meters. This involves calculating the gravitational potential energy change, which can be expressed as pressure loss. Next, account for the pressure change when the hose widens to 4.00 cm in diameter.
This involves understanding the relationship between the hose diameter and fluid velocity, considering the Bernoulli principle and fluid dynamics. Finally, calculate the total pressure loss by summing up the pressure drops from both the height change and the diameter widening. This total pressure loss can then be converted to average friction loss PSI by considering the length of the hose and other relevant parameters.
