Answer:
v = 40 m/s
Explanation:
Difference in the height of the two columns:
Air density, 
Water density, 
The velocity of air flow is given by the equation:
Answer: a) 0.948 b) 117.5µf
Explanation:
Given the load, a total of 2.4kw and 0.8pf
V= 120V, 60 Hz
P= 2.4 kw, cos θ= 80
P= S sin θ - (p/cos θ) sin θ
= P tan θ(cos^-1 (0.8)
=2.4 tan(36.87)= 1.8KVAR
S= 2.4 + j1. 8KVA
1 load absorbs 1.5 kW at 0.707 pf lagging
P= 1.5 kW, cos θ= 0.707 and θ=45 degree
Q= Ptan θ= tan 45°
Q=P=1.5kw
S1= 1.5 +1.5j KVA
S1 + S2= S
2.4+j1.8= 1.5+1.5j + S2
S2= 0.9 + 0.3j KVA
S2= 0.949= 18.43 °
Pf= cos(18.43°) = 0.948
b.) pf to 0.9, a capacitor is needed.
Pf = 0.9
Cos θ= 0.9
θ= 25.84 °
(WC) V^2= P (tan θ1 - tan θ2)
C= 2400 ( tan (36. 87°) - tan (25.84°)) /2 πf × 120^2
f=60, π=22/7
C= 117.5µf
Charging the system is being discussed. Technician A is correct and Technician B is incorrect because overcharging can cause the system to reduce it capacity, but it does not reduce its cooling efficiency.
<h3>What is a coolant?</h3>
The coolants are the liquid that are present in machines to prevent the heating of the system or machines. Because machine and cars run they generate lots of heat that why there are coolants present.
Thus, the correct option is Technician A.
