1 Bulk flow—Pressure difference Plant Physiology UNI 2009

2 Pressure difference Pipe #1 Pressure = +1 bars Liquids: both positive pressure Valve (closed) X Pipe #2 Pressure = +3 bars What happens when we open valve?

3 Pressure difference Pipe #1 Pressure = +1 bars Valve (open) Pipe #2 Pressure = +3 bars Bulk Flow from higher to lower pressure Pressure difference = ? ( ) Liquids: both positive pressure

4 Pressure difference Pipe #1 Pressure = -2 bars Valve (closed) X Pipe #2 Pressure = -5 bars What happens when we open valve? Liquids: both negative pressure

5 Pressure difference Pipe #1 Pressure = -2 bars Liquids Valve (open) Pipe #2 Pressure = -5 bars ( ) Bulk Flow from higher to lower pressure Pressure difference = ?

6 Pressure difference Pipe #1 Pressure = +1 bars Valve (closed) X Pipe #2 Pressure = -4 bars What happens when we open valve? Liquids: one negative pressure one positive pressure

7 Pressure difference Pipe #1 Pressure = +1 bars Valve (open) Pipe #2 Pressure = -4 bars ( ) Liquids: one negative pressure one positive pressure Bulk Flow from higher to lower pressure Pressure difference = ?
