Answer:
Explanation:
First, we have to calculate the gel's column height using the cylinder's volume, as follows:
Then, as the pressure given at the bottom of the tank is the sum of the surface pressure and the gel's column pressure, we need to calculate only the gel's column pressure:
ft of water is a unit of pressure, but we need to convert it to atm and then to Pa, in order to calculate our results in the correct units. Therefore, the conversion factor is:
1 ft of water (4°C) = 0.0295 atm
Now, to calculate the specific gravity, we need to find first the gel's density:
The specific gravity of the gel is 3.75.
<h2>Let us find the efficiency : Ans = 0.6</h2>
Explanation:
we know :
efficiency = output/input
We also know that :
output = m x g x h
where :
m = mass of body
g = acceleration due to gravity
h = height of body from floor
Thus, output = 0.6 x 10 x 1.2 = 7.2J
Similarly ,input = 0.6 x 10 x 2 = 12J
Thus efficiency = 7.2/12 = 0.6
Answer:
The power consumed by the air filter is 9.936 watts
Explanation:
It is given that, the secondary coil of a step-up transformer provides the voltage that operates an electrostatic air filter.
Turn ratio of the transformer,
Voltage of primary coil,
Current in the secondary coil,
The power consumed by the air filter is :
...........(1)
For a transformer,
So,
So, the power consumed by the air filter is 9.936 watts. Hence, this is the required solution.
