Answer:
Do you mean 4m^3 and 3.0 tones?
Explanation:
solution:
Mass = m = 3.0 tones
- 1 ton = 1,000 kg
= 3.0 × 1,000
= 3,000 kg
volume = v = 4m^3
Required:
Mass density of oil = p = ?
We know that;
[tex]p = \frac{mass}{volume} = \frac{m}{v} = \frac{3000}{4} = 750kg |m^{3} ans [/tex]
The answer is:
750kg / m^3
In a modern industrial plant the most likely polyphase power system in use is a/an blank system
Answer:
three-phase
Explanation:
2-phase, 3-phase, and 6-phase systems are in use. The most common of these is 3-phase.
A modern industrial plant most likely uses a 3-phase system.
__
Additional comment
Serious research began on 6-phase power transmission systems in 1973. They have been shown to increase power transfer, and to reduce corona, magnetic fields, and audio noise compared to 3-phase systems. However, they are not in widespread industrial use.
For flow of a liquid metal through a circular tube, the velocity and
temperature profiles are u(r)=2Um[1-(r/ro)2] and T(r) - Ts
= C2 [1 – (r/r0)2],respectively, where C2 is constant. What is the value of the Nusselt
number NuD at this location?
Answer:
Known: Form of the velocity and temperature profiles at a particular axial location for flow in a circular tube. Find: Nusselt number at the prescribed.
