Cooling water is fed by gravity from an open storage tank where the water level is 20 ft above the ground through 100 ft of 1 ½ inch ID steel pipe (light rust), to a heat exchanger at ground level. If the pressure entering the heat exchanger must be 5 psig for it to operate properly:

(a) Ignoring the kinetic energy change, what is the water flow rate through the pipe?
(b) After ignoring the kinetic energy, validate whether this was a good assumption.

Avolcano erupts next to a grassland area in a valley. a. describe three ways in which material released by the volcano could impact the grassland area. b. describe three ways in which the grassland ecosystem could recover after a volcanic eruption.

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.

If the area of a square has increased by a factor of 16, by how much has each side increased?
