In order to provide a steady flow of water to small plants in
your garden, you have decided to build a DIY homemade watering
system. You have your watering sytem by taking several 5 gallon
buckets and drilled a 1/8" hole at the very bottom of each
bucket.In this way, water will use gravity to flow out when
watering your plant.
The cheapest and convenient bucket you found at a convenient
store has a shape of a truncated cone as...

A fluid of density 1300 kg/m3 flows out through a 3 meter diameter pipe without friction at a rate of 1500 L/s. Find the velocity of the fluid as it flows out of the 3 meter diameter pipe. Note that the 'speed' sensor does not give enough significant figures... use the sensor, to prove your calculations (and not the opposite!) Submit Answer Tries 0/99 Calculate the velocity of the fluid if the pipe constricts to a diameter of 1 meter....

Questions 1 and 2
Ionescent molten lava. Living LIVE II only a limited portion of the Earth's temperature range. In fact, the activities of life are possible only in the range from around 0°C (the freezing point of water) to 100°C (the boiling point of water). Of course, there are always exceptions to this rule. In some instances, life can survive at temperatures well below freezing and some organisms are adapted to very high temperatures.

L 2. Steady statemass balance: Water is flowing at steady state in a 0.1 meter-diameter pipe with a maximum velocity (turbulent profile) of 0.3 meters/sec. The pipe then goes through an expansion, to where it is then flowing in a 0.5 meter-diameter pipe, and the flow regime has changed from turbulent to laminar. In the second section of pipe, calculate the velocity as (a) block flow profile (Vavg), and (b) maximum velocity in laminar flow profile? HINT: you will need...
