Question and answer
A pipeline of radius 5 cm carries water at velocity 2.4 m/s. Determine flow rate.
Q = n r² v r = 0.05 m v = 2.4 m/s r² = 0.05² = 0.0025 Q = 3.1416 × 0.0025 × 2.4 Q = 0.01885 m³/s

Q = n r² v
r = 0.05 m
v = 2.4 m/s
r² = 0.05² = 0.0025
Q = 3.1416 × 0.0025 × 2.4
Q = 0.01885 m³/s

Determine input fuel power.
Pout = × Pin
Pout = 2.5 MW
= 0.82
Pin = Pout / n
Pin = 2.5 / 0.82
Pin = 3.05 MW

Determine average velocity of spacecraft.
Distance = 3.2×10 km = 3.2×10 m
Time = 4.5 h = 4.5 × 3600 = 16,200 s
v = d / t
v = 3.2×10 / 16,200
v = 19,753 m/s

Given
r=2.4 m
h=5.6 m
V=nr^2h
=n(2.4)^2x5.6
=n(5.76)x5.6
=32.256n m^3

Determine bending moment at center of simply supported beam.
M = (P × L) / 4
P = 8 kN = 8000 N
L = 6 m
M = (8000 × 6) / 4
M = 48,000 / 4
M = 12,000 N·m

Determine remaining moles of reactant A.
Initial = 120 mol
Conversion = 75% = 0.75
Remaining = 120 × (1 - 0.75)
Remaining = 120 × 0.25
Remaining = 30 mol
