Capillary pressure is defined as Pc=PnwPw and for water saturation decreasing, Pnw outside the pore throat is greater than Pw inside the pore throat, resulting in a positive pressure. A theoretical model for this novel mode of propulsion is developed and used to rationalize the climbers characteristic body postures and predict climbing trajectories consistent with those reported here and elsewhere. Reading a meniscus properly is important for lab safety, since mixing incorrect amounts of materials can be dangerous. information submitted for this request.
