Answer Explanation :

ADVANTAGES OF ISOTHERMAL PROCESS

  • EASE OF MAINTENANCE: there is absence of direct contact between the combustible gas mixture and all moving part in this process
  • LESS NOISE : These engines does not have valves so it is very simple in construction and produce less noise
  • BETTER PERFORMANCE : these engine have better performance than other engines
  • LOW TEMPERATURE : these engine can work on low temperature which is also an advantage

DISADVANTAGES OF ISOTHERMAL PROCESS :

  • GREATER VOLUME AND GREATER WEIGHT: These engine require large volume and large weight
  • SLOWER START: In this process the engine have very slower start which is a disadvantage
  • HIGHER ECONOMIC COST : In this process we need more money this is also an disadvantage

Water at 200C flows through a pipe of 10 mm diameter pipe at 1 m/s. Is the flow Turbulent ? a. Yes b. No
Degger [83]

Answer:

Yes, the flow is turbulent.

Explanation:

Reynolds number gives the nature of flow. If he Reynolds number is less than 2000 then the flow is laminar else turbulent.

Given:

Diameter of pipe is 10mm.

Velocity of the pipe is 1m/s.

Temperature of water is 200°C.

The kinematic viscosity at temperature 200°C is 1.557\times10^{-7}m2/s.

Calculation:

Step1

Expression for Reynolds number is given as follows:

Re=\frac{vd}{\nu}

Here, v is velocity, \nu is kinematic viscosity, d is diameter and Re is Reynolds number.

Substitute the values in the above equation as follows:

Re=\frac{vd}{\nu}

Re=\frac{1\times(10mm)(\frac{1m}{1000mm})}{1.557\times10^{-7}}

Re=64226.07579

Thus, the Reynolds number is 64226.07579. This is greater than 2000.

Hence, the given flow is turbulent flow.

technician a says that hydrogen exists by itself in nature. technician b says that hydrogen has better specific energy than foss
Nikitich [7]

Technician b says that hydrogen has better specific energy than fossil fuels. so technician b is correct.

<h3>Does hydrogen have the highest specific energy?</h3>
  • Although hydrogen has the highest energy density per mass of any fuel, it has the lowest energy density per unit volume due to its low ambient temperature density, necessitating the development of new storage technologies with the potential for higher energy density.
  • Hydrogen is utilized as a rocket fuel and in fuel cells to generate power on some spacecraft because it is beneficial as an energy source or fuel due to its high energy content per unit of weight.
  • Since hydrogen has a significantly higher energy content than fossil fuels, less of it is required to carry out any given task.

State two main consumers of electricity transmitted at low frequency Calculate the primary voltage of a transformer if the prima
bagirrra123 [75]

Answer:

1) a. Customers requiring AC electric power transmission for powering remote devices which may include a subsea transmission system where power is distributed to subsea devices

b. Customers that utilize commutator-type motors

2) The primary voltage is 150 volts

Explanation:

The parameters given are;

Number of primary winding, N_p = 50 turns

Number of secondary winding, N_s = 150 turns

Voltage in secondary winding, V_s = 450 volts

Voltage in primary winding = V_p

The relation between N_p, N_s, V_s and V_p is as follows;

\dfrac{V_p}{V_s}  = \dfrac{N_p}{N_s}

Which gives;

V_p  = \dfrac{N_p \times V_s}{N_s}

From which we have;

V_p  = \dfrac{50\times 450}{150} = 150 \ volts

The primary voltage = 150 volts.
