Question

Using the figure below, please answer the following:

B-90 :300pm: CBV #1 CBV #2 =900 : : β= 120° : 200μm Hm: CBV #3 CBV #4

Pictured above are capillary burst valves(CBV) for a microfluidic chip.

(a) Please find the bursting pressure for each of the CBVs if the chip made from PMMA has a height of 100µm(lets assume that water is used inside the channels)

(b) If CBV #2 has a bursting pressure of 1kPa, what is θ(liquid-solid contact angle)?
