- Daughter's age=x
- Father's age=6x
10years after
- Daughter's age=x+20
- Father's age=6x+20
ATQ
- Father's present age=6x+10=6(5)+10=30+10=40yrs
- Daughter's present age=x+10=5+10=15yrs
3. Determine the bulk temperature, center line temperature, and surface temperature for a laminar flow in a 2 cm inner diameter
tube with defined velocity and temperature profiles: a. u=0.1[1-(r/0.01)^2] m/s b. T=400-3x10^6(1.875x10^-5-0.25r^2+624r^4) K c. Calculate the heat flux at the wall and the Nusselt number if the fluid is water (look up the property of water) d. Calculate the pressure drop in the tube over 10 cm.
