10) A shower pipe at the beach that is 10 cm in diameter carries
water (density 1000 kg/m3 ) up a height of 2.0 m, at which point
the pipe narrows to 5 cm and continues another 0.50 m up before the
water squires out of the pipe 2.5 m above where it started. Ignore
viscosity.
a) If the water moves at 1.5 m/s in the wider part of the pipe,
what is its speed in the narrower part of...
A fuel mixture consists of 90% octane
(C8H18) and 10% ethyl alcohol
(C2H5OH), by volume. This fuel mixture is
burned with 200% theoretical dry air in a combustion chamber at
atmospheric pressure.
a) Write the balanced reaction equation for complete combustion
of this fuel mixture.
b) Determine the theoretical air-fuel ratio.
c) Actual air-flow rate for a fuel mixture flow rate of 5 kg/s.
d) Calculate the molar mass of the mixture product gases.

How
to calculate density of mixture flowing through pipe, with 50%
volume of one fluid and 50% volume of another fluid?
Then for the mixture if temperature, internal diameter and
pressure gradient is given. 1.Calculate Reynolds number
2. Volumetric flow rate
3. Local velocity at a perpendicular distance of X from inner
wall of pipe.

Boudreau, a resident of Louisiana, carries the minimum required
PAP liability limit of 10/25/10. While on vacation in
Massachusetts, Boudreau strikes a pedestrian with his car,
resulting in medical costs for the victim of $45,000. Massachusetts
law requires motorists to maintain liability limits of 20/40/15.
Which of the following statements concerning this situation is
correct?
Boudreau's insurance company will only pay $10,000 towards the
victim's medical costs.
Boudreau is subject to arrest or citation for failing to
