Tutorial 1

1. Write a program to calculate

a. Area of a circle

b. Reynold number

where,

D = 2 in. , v = 10 ft/s , ( = 62.4 lb/ft3 , ( = 0.3 lb/(hr(ft)

c. Heat capacity

Cp = 6.945 + 10.01 x 10-3 T 3.794 x 10-6 T2

when T = 400 K. Cp has the unit of cal/(g mol(K).

2. Prepare an innovative program to calculate the following heat capacity problem using function block (Fcn).

Cp = 6.9 + 0.02884 x 10-2 T + 0.02429 x 10-5 T 2 -0.08052 x 10-9 T 3Tutorial 2Introduction Familiarization with Simulink blocks
