Actual exam question for OMG's OMG-OCSMP-MBI300 exam

Question #: 62
Topic #: 6

Choose the correct answer.

A system engineer has created the following model of a tank system composed of two tanks and a pipe connecting them:

The system engineer wants to mathematically relate the flow of water through the pipe using the following mass conservation equation: Tank_System wFlowin flowRate * Tank_System pipe endA_Area = Tank_System wFlowOut flowRate * Tank_System pipe endB_Area How would the system engineer model this in SysML?

ACreate a block to represent the mass conservation equation, use it in Tank_System. and relate its properties to the properties of wFlowin. wFlowOut. and pipe

BCreate a constraint block to represent the mass conservation equation, use it in Tank_System. and relate its parameters to the properties of wFiowin. wFlowOut. and pipe

CCreate a constraint block to represent each of wFlowin wFlowOut and the mass conservation equation; use these constraint blocks In Tank_System. and relate their parameters to the properties of pipe.

DCreate two flow properties for Tank_System (equivalent to wFlowin and wFlowOut); create a constraint block for the mass conservation equation and use it in Tank_System. and then relate the flow properties to the new constraint property.

EIt is not possible to model this because wFlowin and wFlowOut are item properties and not flow properties

I bet the system engineer who created this model is feeling pretty 'tank-ful' right about now.

Option E? Really? Next they'll tell us we can't model gravity because it's an 'item property' and not a 'flow property'.

Personally, I'd go with Option D. Creating the flow properties and a separate constraint block seems like a more modular and flexible approach.

Option E is definitely not the right choice, since we need flow properties for this model.

I think Option A could also work well, by creating a block to represent the mass conservation equation.

I agree, Option D seems like the best choice for modeling the system.

I agree, Option B is the best choice here. Modeling the equation as a constraint block and relating it to the system properties is a clean and efficient approach.

Option B seems the most straightforward way to model this. A constraint block representing the mass conservation equation can be easily related to the relevant properties of the system.
