Description: An apartment building has a pumped ring main that circulates hot water at 75 C through insulated 40 mm pipe with he

at loss of 17 Watts/metre. At each apartment, this hot water is mixed with cold water to a delivery temperature of 50C? One of the sub-questions provides extra info: It takes 0.00119 kWh/degree/litre to heat water from 15C to 50C.
My problem:

With typical water-efficient shower and taps, typical Melbourne usage of hot water is 44 litres/day/person. For typical occupancy of 1.8 people, what is the effective efficiency of this hot water distribution system (for simplicity assume the existing heating system feeding the distribution system is 100% efficient).? Note that this efficiency calculation ignores the efficiency of production of hot water.

If anyone can help me or if anyone has any idea that would be great!

Thanks :)

goldenfox [79]

The relationship between Agile and DevOps is that: A. iterations of new increments of software use requirements developed by DevOps.

<h3>What is Agile software development?</h3>

In Agile software development, the software development team are generally more focused on the production of working (active) software programs with less effort on documentation.

Conversely, the key objectives of DevOps is focused on the ability to deliver software programs and services at high velocity, with higher quality and with built in security.

In conclusion, the relationship between Agile and DevOps is that iterations of new increments of software use requirements are typically developed by DevOps.

A solenoid with a length of 20 cm and a radius of 5 cm consists of 400 turns and carries a current of 12 A. If z = 0 represents
forsale [732]

Answer:

Copy MATLAB code to plot the magnitude of magnetic field strength with respect to z on the axis of solenoid:

z=-20:0.01:20;

H=120.*(((20-(2.*z))./sqrt((20-(2.*z)).^2+100))+((20+(2.*z))./sqrt((20+(2.*z)).^2+100)));

plot(z,H)

title('plot of |H| vs z along the axis of solenoid')

ylabel('Magnitude of magnetic field 'H")

xlabel('position on axis of solenoid 'z")

Explanation:

full explanation is attached as picture and the resultant plot also.
