System Capacity means the available operational capacity of the System at any applicable point in time, as such amount may vary from time to time pursuant to any contractual arrangements entered into by Carrier.

<h3>What is capacity of a production system?</h3>

Production capacity is the maximum possible output of a manufacturing business, measured in units of output per period. Knowing your production capacity gives you the chance to better plan and schedule production, give more accurate lead times, and forecast your cash flow.

<h3>What is an example of capacity?</h3>

The definition of capacity is the ability of someone or something to hold something. An example of capacity is how many people can fit in a room. An example of capacity is the amount of water a cup can hold.

A cartridge electrical heater is shaped as a cylinder of length L=200 mm and outer diameter D=20 mm. Under normal operating cond
Setler79 [48]

Answer:

When water is surrounding T_s = 34.17 degree C

When air surrounding T_S = 1434.7 degree C

from above calculation we can conclude that air is less effective than water  as heat transfer agent

Explanation:

Given data:

length  = 300 mm

Outer diameter  = 30 mm

Dissipated energy = 2 kw = 2000 w

Heat transfer coefficient IN WATER = 5000 W/m^2 K

Heat transfer coefficient in air  = 50 W/m^2 K

we know that q_{convection} =  P

From newton law of coding we have

q_{convection} =  hA(T_s -  T_{\infity})

T_s is surface temp.

T - temperature at surrounding

P = hA(T_s -  T_{\infity})[tex]\frac{P}{\pi hDL} =  (T_s -  T_{\infity})

solving for[/tex] T_s [/tex] w have

T_s = T_{\infty} + \frac{P}{\pi hDL}

T_s = 20 + \frac{2000}{\pi 5000\times 0.03\times 0.3}

T_s = 34.17 degree C

When air is surrounding we have

T_s = T_{\infty} + \frac{P}{\pi hDL}

T_s = 20 + \frac{2000}{\pi 2000\times 0.03\times 0.3}

T_s = 1434.7 degree C

from above calculation we can conclude that air is less effective than water  as heat transfer agent

Entropy change is evaluated using Eq. 6.2a based on an internally reversible process. Can the entropy change between two states
Vadim26 [7]

Answer:

YES

Explanation:

Entropy is an extensive property of the system entropy change that value of entropy change can be determined for any process between the states whether reversible or not. i have attached the formula to calculate entropy change which is independent of whether the system is reversible or not and can be determined for any process.

dalvyx [7]

Answer:

(a) Calculate the field, armature, and load currents versus load = 306A

(b) Determine the terminal voltage at no-load and at rated load conditions = 300V

(c) Calculate the voltage regulation of the generator. Use the no-load voltage as the base value = 6.67%

(d) Plot the terminal voltage as a function of the load. Determine the load that corresponds to a 5% voltage drop using the no-load voltage as the base = 294.74V
