Answer #1

TRUE

Expanding hoses are designed in such a way that it has two layers to it. One an inner tube through which water flows and an outer fabric which is usually made of nylon. The inner tube can be made of elastic rubber.

When water is flow through one end, the other end of the hose which has a shut off valve is turned off, so that water is blocked from one end and when the pressure builds up inside the inner tube, the inner tube starts to expends and reaches it full expanding length. After which shut off is turned on and the hose works like just a normal garden hose.

What is the purpose of the NaOH used in the reaction to make nylon from a diacyl chloride? Why do the methylene chloride and hexane solutions form two layers? (Are hexane and methylene chloride immiscible? Try it!) Why can’t you calculate the yield of nylon in moles (the usual unit used for % yield)? For industrial nylon manufacturing, would you use the di-acid or the di-acyl chloride? Why?

A horizontal garden hose has a pressure of 220 kPa when the nozzle is closed, so the water isn’t moving. If it develops a leak that causes water to spray directly upward, how high will the water go?

True/False ___ Poisson regression is used when a count variable is regressed onto a set of continuous and/or categorical predictors. ___ Ranks are never considered preferable to the actual data. ___ When using a parametric test if two groups have identically skewed distributions with the same variance, then any differences would be due to differences in location. ___ A rank-based test may be considered a robust alternative because it is testing a null hypothesis similar in concept to the parametric...

(a) What is the pressure drop due to the Bernoulli effect as water goes into a 2.70-cm-diameter nozzle from a 8.90-cm-diameter fire hose while carrying a flow of 41.0 L/s? N/m2 (b) To what maximum height above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.) m
