1.For water at 25°Cflowing in a pipe with a 2 cm diameter and 1 m length,determine:
if the flow laminar,turbulent, or transitional, when the average velocity is 0.142m/s.
2.What is the reynold's number for water flowing in a 24 inch circular pipe at a velocity of 6.21 ft/s? is the flow laminar or turbulent and what is the velocity head of the flow?
3.In older houses one will often find steel waterpipings whereascopper tubing is now generally used. While carrying out renovationsplumbers often interconnect the steel pipings with Copper tubings.Is this a sound practice? Explain.
A channel of a rectangular section is to take a certain discharge Q at critical flow; prove that for the wetted perimeter, P=b+2y to be minimum, the water depth must be three-quarters of the width
A particular unit cell is cubic with ions of type A located at the corners and facecenters of the unit cell and ions of type B located at the midpoint of each edge of the cube and at the body centered position.
A wastewater treatment plant produces 34, 500 pounds of secondary sludge each day. Wastewater flows into the plant at a rate of 5.6 MGD and has an influent BOD of 325 mg/L. How many pounds of BOD are destroyed by this plant each day
The coefficient of static friction between each crate and the ground is 0.25 The crates are next to each other connected by a rope and then from the other end one has a P force going up at an angle of 30 degrees
To determine the effect of fuel grade in fuel efficiency, 80 new cars of the same make with identical engines, were each driven for 1000 miles. Forty of the cars ran on regular fuel, and the other forty received premium grade fuel.

The frame is designed to carry the hanging mass at G equal to 167 kg. The frame is supported by a pin connection at C and the rope AB, and constructed with pin connections at points E, F, and D. Importantly, members BEFG and EDC are continuous mem..
A particle is traveling in a straight line at a constant speed of 22.9 m/s. Suddenly, a constant force of 10.7 N acts on it, bringing it to a stop in a distance of 63.6 m.
The solids in a specimen have a specific gravity of 2.65. If the oven-dry mass of the specimen is 25kg, what is the volume of the solids in it
Consider a small town in the Phillippines, where the average weight of people is 55 kg, and the average lifespan is 60 years. The people here eat lots of fish due to abundant availability from the local river.
Argon gas is heated in a constant pressure process from 20.0 to 500.°C. Assuming ideal gas behavior, determine: a. The ratio of the final to initial volumes. b. The change in specific internal energy. c. The change in specific enthalpy of the argon.
