Check below for answers and explanations
Explanation:
Automation is a technology by which processes that are normally meant to be controlled by humans are electronically controlled. These can be through the use of robots, computer aided machines, etc.
For small scale industries, expensive automation should not be employed, it should rather be low cost, because of the financial abilities of these firms.
Low cost automation will improve the production of small scale industries in limited time. Humans cannot match up with machines that have been incorporated with programmable comptrollers in carrying out production processes. Such machines operate at a higher speed and Efficiency.
For example, In a small packaging company, microrobots can be made to serve this purpose while saving the continual cost of labour and at the same time ensuring efficiency.
A small mechanic workshop that decides to employ an automatic diagnostic tool will be more efficient and productive than the one that uses manual approach.
Answer:
k = 0.1118 per min
Explanation:
Assume;
Initial number of bacteria = N0
Number of bacteria IN 'T' time = Nt
So,
k = 0.1118 per min
Answer:
The pressure in tank will become 541.3 KPa.
Explanation:
From general gas equation we know that:
PV = nRT
PV = (m/M)RT
P/Tm = R/VM
Now, for initial state:
P1/T1 m1 = R/VM ______ eqn (1)
For Final State, as the gas constant (R), volume (V) and molecular mass of air (M) remains constant;
P2/T2 m2 = R/VM ______ eqn (2)
Comparing eqn (1) and eqn (2):
P1/T1 m1 = P2/T2 m2
Now, we have:
P1 = 400 KPa
P2 = ?
m1 = 2 kg
m2 = 0.6 kg + 2 kg = 2.6 kg
T1 = 20°C = 293 K
T2 = 32°C = 305 K
Therefore,
(400 KPa)/(293 K)(2 kg) = P2/(305 K)(2.6 kg)
<u>P2 = 541.3 KPa</u>
