Answer:
Kieran is a Carpenter, and Kurt is a Drafter
Explanation:
Among all the professions listed, Kurt can only possibly be a Drafter. A Drafter is an engineering technician who makes detailed technical drawings or plans for machinery, buildings, electronics, infrastructure, sections, etc. Drafters make use of computer software and manual sketches to convert the designs, plans, and layouts of engineers and architects into a set of technical drawings. All the other professions will at some point need for the professional to stand and work at an height above the ground except for a drafter, whose feet will remain on the ground at almost all times.
Answer:
option C
option A
Explanation:
Enthalpy gained by air= 1023-290
= 733 kJ/kg
Rate of energy gain= mass flow rate × Enthalpy gained by air
= 0.1 × 733
= 73.3 kJ/s
rate of heat transfer between compressor and air= 77kW
Heat loss by air to surroundings= 77-73.3
=3.7kW
Enthalpy lost by steam in turbine= 1407.6-1236.4
= 171.2 Btu/lb
Rate of energy transfer to turbine= Enthalpy lost by steam× mass flow rate
= 171.2×5
= 856 Btu/s
Net rate of energy transfer to turbine=rate of Energy transfer to turbine- rate of heat transfer to turbine
= 856-40
= 816 Btu/s

Explanation:
Which stroke in the four stroke cycle begins as the piston reaches BDC after combustion takes place?
Answer :Exhaust stroke is the waste gasses discharging process into the atmosphere after the combustion stroke. This step takes place after the piston reaches the BDC at the end of the combustion stroke. When the piston reaches BDC, the piston will definitely move back to TDC.
