Question 22

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:

Question # 22

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?

Options:

A.

Create 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

B.

Create 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

C.

Create 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.

D.

Create 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.

E.

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

Question 23

Choose the correct answer

How ate use cases and requirements used for requirements analysis in SysML?

A.

in a SysML model, either use cases or requirements are modeled, but never both

Question 26

Choose the correct answer.

The formula for the determinant of a square 2X2 matrix.

|ab|

|cd|

is a'd-b'c A subsystem receives one message for each value (i e. a(v) b(v). c(v) and d(v) where v is a real number) These messages can be in any order, and the ensure sequence is followed by an "end" message. The subsystem must calculate the determinant and output it upon receipt of the end message If there are multiple messages for one value (e g . two a(v) messages), or the end message is received before all values have been received, the subsystem should signal an error.
