for the following data marks of 50 students given below find U=1

1.1 kg of air at 261°C is allowed to expand isothermally until the volume doubled. Then heat is then rejected by at constant pressure until the volume is the same as it was initially. Determine; a. the net heat flow b. the overall change of entropy. c. Sketch the processes on a T-s diagram

A block centered grid type is selected for a 1-D reservoir. Flow is in X

direction. Rock and fluid are assumed as incompressible. The total length

of the reservoir is 500 ft. Following information is known:

Ay=100 ft

AZ=10 ft

4=2 cp

B=1 (stb/bbl) S=2 IN= 0.5 Nt

AX= 20 ft

Ax2=50 ft

Ax,= 100 ft Ax,= 150 ft Axs= 180 At

Kx1=50 md Kx2=60 md Kx=40 md Kx-50 md Kx5=30 md

Ky= 70 md for all blocks block# 3: injection well block# 4: production well

please my freind i want to be to use multiple crank slide or similar mechnism to drive multiple objects but I dont want to use crank slider for each object. How can I drive them all from one single point.

many thanks and forgive for my ignorance if i used the wrong ords i the question

Steam is delivered to turbine at 5.4 Mpa and 610℃. Before condensation at 30℃, steam is extracted for feedwater heating at 0.1 Mpa. For an ideal regenerative cycle, find the thermal efficiency.

1.   A turbine is supplied with steam at 40 bar, 400^oC, which expands through the turbine in steady flow to an exit pressure of 0.2 bar, and dryness fraction of

0.93. The inlet velocity is negligible, but the steam leaves at high velocity through a duct of 0.14m² cross-sectional area. If the mass flow is 3 kg/s, and the mechanical efficiency is 90%, calculate the power output of the turbine. Show the process is irreversible and calculate the change of entropy. Heat losses from the turbine are negligible. Sketch TS diagram.

when does a signal is said to be valid or invalid?

The I-beam design must satisfy the following requirements:

Maximum beam must not exceed the allowable stress.

Maximum deflection of the beam must not exceed the allowable stress.

Load which will be carried by the crane: 10026 Kg

Distance between the concrete walls: 14 meters

Distance from the ends of the track on which the trolley cannot run due to other machinery: 1.0 meters

Allowable normal stress in the I-beam: 260 MPa

Allowable beam deflection: 21 meters

The project will be assessed using the folllowing categories.

Conceptualise

Sketch the problem, showing relevant geometry, dimensions, support and loadings

Sketch e.g.: FBD or stress element as applicable

Identify Boundary conditions and other support conditions

Categorise

Identify problem type, solution strategy, relevant criteria and analyses

Write the governing equations

Identify unknowns

Make necessary assumptions

Identify material properties

Analyse

Solve the governing equations

Solve for unknowns or formulate problem to allow solution

Input a positive integer.

Using while() loop, repeatedly print out the message "CodeChum is awesome" for the same number of times as that of the inputted integer. Each outputted message must be separated in new lines.

Don't forget to make an increment/decrement variable that will increase/decrease its value per iteration so as to not encounter a forever loop and have errors, okay?
