A smooth pipe consists of 8 m of 120 mm diameter pipe followed by 15 m of 300 mm diameter pipe with an abrupt change in cross-section at the junction as shown in Figure 1. The entrance of the pipe is chamfered, and the discharge is submerged. The pipe carries water at a velocity of 7.8 m/s in the smaller pipe. If the water temperature is 15 °C with a viscosity of 1.139 x 10-3 m²/s, use the moody chart and calculate the total head loss in the pipe. Consider the entrance and exit losses. 15 m 120mm 8m 300 mm

Question
A smooth pipe consists of 8 m of 120 mm diameter pipe followed by 15 m of 300 mm
diameter pipe with an abrupt change in cross-section at the junction as shown in Figure
1. The entrance of the pipe is chamfered, and the discharge is submerged. The pipe
carries water at a velocity of 7.8 m/s in the smaller pipe. If the water temperature is 15
°C with a viscosity of 1.139 x 10-3 m²/s, use the moody chart and calculate the total
head loss in the pipe. Consider the entrance and exit losses.
