The two ways you can use to make an informal survey are:
- make field observations
- interview people using informal unstructured techniques
<h3>What are informal surveys?</h3>
In informal surveys can be regarded as a type of survey that can be made by the researcher by going to the field themselves and this can be done by using different methods or ways.
For instance, the researcher can go out to interview people that can give the data that is needed about the research such as informally asking them questions, unstructured techniques can also be used to solve critical issues.

Answer:
5.118 m^3/hr
Explanation:
Given data:
viscosity of cell broth = 5cP
cake resistance = 1*1011 cm/g
dry basis per volume of filtrate = 20 g/liter
Diameter = 8m , Length = 12m
vacuum pressure = 80 kpa
cake formation time = 20 s
cycle time = 60 s
<u>Determine the filtration rate in volumes/hr expected fir the rotary vacuum filter</u>
attached below is a detailed solution of the question
Hence The filtration rate in volumes/hr expected for the rotary vacuum filter
V' = (
) * 1706.0670
= 5118.201 liters ≈ 5.118 m^3/hr
Answer:
Method B is the more efficient way of heating the water.
Explanation:
Method B is more efficient because by placing a heating element in the water as in described in method B, the heat that is lost to the surroundings is minimized which implies that more heat is supplied directly to the water. Therefore, more heating is achieved with a lesser amount of electrical energy input. Whereas placing the pan on a range means more heat losses to the surrounding and as such it will take a longer time for the water to heat up and also take more electrical energy.

Answer:
a) 244,140,625 different ways
b) 390,625 different ways
Explanation:
a) If there are 5 ways to place a chip on each location, and there are 12 locations overall, we have:
5^12 ways of placing them
This would mean a total of 244,140,625 different ways
b) If five chips are of the same type, we can first find how many ways we can place chips on the remaining 7 locations:
5^7 = 78,125
Next we can multiply this by the number of ways the next 5 chips could be the same:
78,125 * 5 = 390,625 different ways
