Homework Statement Express the function Y= (abd + c)' + ((acd)'+(b)')' as the complete disjunctive normal form: 2.1 by applying Boole's theorerm, Homework EquationsThe Attempt at a Solution I separated the equations to two terms (T1,T2) T1= (abd + c)' T2=((acd)'+(b)')' T1= (abd+c)'...

Can someone tell me why he wrote m_dot*Q_out ? the equation given is P=m(h_2-h_1)

No I understand the description. But I don't understand the form of writing the code . Why in the first line he wrote units -500 and why in the second line he wrote units - 1000

I cannot Understand the marked lines

When is the rate of change of momentum equals zero ?

I want to know if the velocity profile is uniform for viscous fluids or not ?

1. The problem statement, all variables and given/kno wn dataHomework EquationsThe Attempt at a Solution

now I know if I didn't find a table for a specific pressure I should interpolate .Do I understand correctly ?

Why what ? Why it works here ?

h(250C,1.5MPa)=2899.3+((250-240)/(280-240))*(2991.7-2899.3)=2922.4

Table for 1.0MPa : Table for 1.5MPa: T=240,h=2920.4 T=240,h=2899.3 T=280,h=3008.2 T=280,h=2991.7

No I know it but like I said before I'm not familiar with it because my teacher doesn't use this method. That's all

That's the question. Which table ? I don't have a table for the pressure 1.1MPa . I have for 1.0 MPa and for 1.5 MPa
