A chocolate chip gets momentarily stuck halfway up Misha's straw, though the milkshake can still flow smoothly past. As it flows past the chocolate chip, the pressure in the milkshake is (A) lower than if no obstruction were there (B) higher than if no obstruction were there (C) the same as if no obstruction were there (D) can't be determined without more information. Misha and Lakshmi are two kids who are enjoying drinks at a fast-food restaurant. Misha is drinking a chocolate chip milkshake through a fat straw of radius 0.3 cm, and Lakshmi is drinking lemonade through a thinner straw of radius 0.2 cm. Lemonade has the viscosity of water, 0.001 Pa-s, while Misha's thicker milkshake has a viscosity of 0.5 Pa-s. The lemonade density we will take as 1000 kg/m³ while the milkshake is 960 kg/m³. Misha's chocolate chips, though have a density of 1300 kg/m³. Both straws are 20 cm long and extend 10 cm above the drink. In order to suck the drinks into their straws, the kids are lowering the pressure in their mouths to 60% of atmospheric pressure by expanding their diaphragms (as is normal).
