Using the data given below, calculate the drop in the temperature of molten aluminum as it flows in a 15 cm long round channel o

f 2 cm diameter in a water-cooled die and what will be the temperature drop if the metal were to flow through a 15 cm long channel having a square cross-section (side = 2 cm) in an identical mold? Assume that Al enters the channel at 800 C. The average flow velocity is 4 cm/s. Given: density of Al=2.2 g/cm3, specific heat of Al=0.28 cal/g.K, mold-metal interface heat transfer coefficient=0.01 cal/cm2.s.K, and the die temperature=27 C (assumed constant).

A higher grade number for oil means it is _____.
fenix001 [56]

Answer:

For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil. The higher number, following the “w” refers to hot weather viscosity, or how fluid your oil is at hot temperatures. The higher the number, the thicker the oil at a specified temperature. so it's B

Given a manhole with the outlet invert elevation of 2605. A run of 48 inch pipe connects to the next manhole at an invert elevat
alexdok [17]

Answer:

Distance between manholes = 166.67 (Unit) (Approx)

Explanation:

Given:

Invert elevation = 2605

New Invert elevation = 2610

Grade % = 3% = 0.03

Find:

Distance between manholes

Computation:

Grade % = (Change in elevation)/Distance between objects

0.03 = (2610-2605)/Distance between manholes

0.03 = 5 / Distance between manholes

Distance between manholes = 166.67 (Unit) (Approx)

Use pseudocode. 1) Prompt for and input a saleswoman's sales for the month (in dollars) and her commission rate (percentage). Ou
aleksandr82 [10.1K]

Answer:

The pseudocode is as follows:

Input SalesAmount

Input CommissionRate

CommissionEarned= SalesAmount * (CommissionRate/100)

Print CommissionEarned

Explanation:

This gets input for SalesAmount

Input SalesAmount

This gets input for CommissionRate

Input CommissionRate

This calculates the CommissionEarned

CommissionEarned= SalesAmount * (CommissionRate/100)

This prints the calculated CommissionEarned

Print CommissionEarned

Explain three examples of workshop
stealth61 [152]

Answer:

Invitational Workshop

An invitational workshop is what many of us know. It’s what Lucy Calkins has made famous through the Reading and Writing Workshop. In the invitational workshop, the instructor usually hosts a minilesson. This minilesson is intended to meet the needs of the majority of children in the classroom. Afterward, the children are “invited” to employ the skills or strategy for the minilesson during workshop time, where students work independently or in small groups
