Choose your exam, inspect the governing method, check an application and test a changed condition. Selected examples include original narration. HVAC lessons pair equipment illustrations with calculation schematics. The PMP preview includes the full first core workshop. No account or payment is required.
Work a fan speed change using one consistent ratio, test the cubic shaft-power demand against a motor limit, and recognize when the installed system needs a new curve intersection.
Open complete lesson →
Combine two identical pump curves at a common head, solve the actual system intersection, and distinguish total system flow from each pump's flow.
Open complete lesson →
Convert real power to apparent power and upstream line current, calculate ideal shunt compensation, and preserve the distinction between supply current and load energy.
Open complete lesson →
Translate roof area load into beam line load, include beam self-weight once and connect equilibrium to shear and moment diagrams.
Open complete lesson →
Calculate each required path, respect the installation merge and distinguish an activity-duration increase from its effect on project completion.
Open complete lesson →Convert three-phase apparent power into current, then compare independent electrical and spatial constraints without trading away either one.
Read complete lesson →For Construction Operations and Methods, also work the earthwork and truckload example →
Measure pressure head below the water table, then subtract pore pressure once.
Open complete lesson →
Add backsights, subtract foresights, and check the independent loop closure.
Open complete lesson →
Water content uses dry-solids mass; dry density uses the full specimen volume.
Open complete lesson →
Keep net installed volume, waste allowance and purchased quantity separate.
Open complete lesson →
Recompute the merge and controlling path before selecting a recovery action.
Open complete lesson →
A wet-density reading cannot be compared directly with a dry laboratory maximum.
Open complete lesson →
Solve both force and moment equilibrium; equal reactions occur when the total vertical-load resultant is at midspan.
Open complete lesson →
Weight runoff coefficients by contributing area, then convert rainfall and area consistently.
Open complete lesson →
Convert slab thickness to feet and multiply total area load by the interior shore tributary area.
Open complete lesson →
Check lateral travel to safe egress, not ladder count, and reassess changing conditions.
Open complete lesson →Build an SI energy balance, distinguish hydraulic output from electrical input, and test how a changed boundary affects the result.
Read complete lesson →Three narrated examples cover ceiling coordination, window-head control layers and an offset-column load path. Each includes captions, a transcript and an application check.
Combine slope, physical service depth and clearance into a coordinated section; select a change that preserves structural and ceiling requirements.
Open complete lesson →
Trace each control function through a window head and document the transition that restores the failed drainage path.
Open complete lesson →
Identify the load-path discontinuity, check a simplified reaction model and request the information needed to coordinate the transfer zone.
Open complete lesson →Watch two narrated project-management decision scenarios: evaluate a requested change and compare schedule-recovery options using value, cost, quality, risk and the stated approval authority. The complete first core workshop is also available below.
Evaluate a requested change using complete impact evidence, alternatives and the project's stated approval authority.
Open complete lesson →
Compare schedule-recovery options using the current controlling branch, feasibility, cost, quality, risk and approval authority.
Open complete lesson →Explain why delivering an output and realizing a benefit are different achievements.
Read complete lesson →Free development preview. All 24 foundation lessons include worked calculations, common errors, handbook navigation and an application check. Paid enrollment is closed.
Two air streams combine through conservation of dry air, moisture and energy. A volume fraction is a mass fraction only under suitable density assumptions.
Open complete lesson →
Thermal capacity sets hydronic flow; the pressure-loss network sets pump head. Elevation means different things in open and closed systems.
Open complete lesson →
Use flow arrangement, capacity rate and area basis to select a defensible heat-transfer method.
