Pressure drop under laminar flow conditions: consider water flowing in a 0.1 m diameter pipe at the laminar flow limit (re# at 2000). what is the average velocity of the water at this condition (provide answer in meters/sec)? what is the pressure drop (kpa) of this flow over a distance of 1,000 meters?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
