A gas turbine operating on a simple Joule cycle has a pressure compression ratio of 8:1. The turbine has a thermal efficiency of 60% of the ideal. Determine the actual thermal efficiency.
A Butchery at Western Cape requires a modularized trolley designed for 300 Kg maximum
load bearing capacity.
The information obtained is as follows:
I. The trolley will be shipped to the location using a drone that can lift 20 Kg maximum load
II. The drone has a standard box compartment measuring 1000 mm length, 600 mm width, and
300 mm depth.
(Assume the square meter weight of most
solid flat sheets suitable for the trolley design is 3 Kg/m2
. Furthermore, assume the following
weights for materials that are available off the shelf:
Bearings: 200 g/bearing
Rubberized wheel: 100 g/wheel
Helical springs: 50 g/spring
Cylindrical shaft: 20 g/mm diametral volume for 1000 mm length
Standard trolley handle: 40 g

A quantity of gas occupies a volume of 0.4M² a pressure of 100KN/M³ and a temperature of 20°C the gas is compressed isothermally to a pressure of 450KN/M² then expanded adiabatically to its intial volume for this quantity of gas determine;
1:the heat transferred during the compression
2:the change of internal energy during the expansion
3:the mass of gas.
