Using excel, estimate the heat loss from 300 ft of 4 nom sch 40 carbon steel pipe carrying 60,000 lb/hr of hot water at 180°f for kapok insulation thicknesses of 0, 0.5, 1, 1.5, 2.0, 2.5, 3.0 in. plot class vs insulation thickness for the following conditions: (a) the pipe is above ground with air temperature as (b), but with a wind velocity of 20 mph. for this equation, use an appropriate nusselt number correlation for a cylinder in crossflow (which you can get from a heat transfer book). (b) the pipe is 10 m below ground with a ground temperature of 50 deg f. the soil has a thermal conductivity of 1.3 btu/hr-ft-r.

Americium-241 undergoes fission to produce three neutrons per fission event. if a neutron-absorbing material is mixed in with this sample so that the rate of neutron production drops down to 1.8 neutrons per fission event, which will be effective at achieving a critical mass? check all that apply. remove a deflective shield surrounding the sample. remove absorbent material mixed in with the sample. compress the sample of americium-241.

What three things does a balanced equation show you?

Movement that is like a t a type of wave that transfers energy where the particles in the medium move in a circle motion while the energy travels left or right. a type of wave that transfers energy where the particles in the medium move perpendicular to the direction in which the energy is traveling. transfers energy from one location to another a type of wave that transfers energy where the particles in the medium move parallel to the direction in which the energy is traveling. movement that is back and forth, like an equal sign = 1. wave 2. parallel movement 3. perpendicular movement 4. transverse wave 5. longitudinal wave 6. surface wave
