1. One end of a cylindrical pipe has a radius of 1.5 cm. Water (density = 1.0×103 kg/m3) streams steadily out at 7.0m/s. The rate at which mass is leaving the pipe is:
1. 2.5kg/s
2. 4.9kg/s
3. 7.0kg/s
4. 48 kg/s
5. 7.0 × 103 kg/s
2. One end of a cylindrical pipe has a radius of 1.5 cm. Water (density = 1.0×103 kg/m3) streams steadily out at 7.0m/s. The volume flow rate is:
1. 4.9 × 10−3 m3 /s
2. 2.5m3 /s
3. 4.9m3 /s
4. 7.0m3 /s
5. 48m3 /s
