For the following (10 times) voltage measured voltage values of a designed power supply:

5.0 4.9 5.1 5.2 5.3 4.8 4.9 4.7 5.0 5.1

Determine:

a. The mean of the voltage readings

b. Average Deviation

c. Standard Deviation

d. The probable errore. Determine the probable error as a percentage.

f. The overall error knowing that the known error in the supply output is

1.5%.​

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?

What is creep? what is stress relaxation?
