PIEAS Test case studies
PIEAS Test · Put your knowledge to work in context.
The PIEAS Admission Test is the entrance examination used by the Pakistan Institute of Engineering and Applied Sciences (PIEAS), Islamabad, a federal public university focused on engineering, natural sciences and formal sciences. The test is administered for applicants to the institute's BS, MS and PhD programs, so candidates at both undergraduate and postgraduate level sit an admission test as part of the selection process. PIEAS describes itself as offering BS, MS, MPhil and PhD degree programs, with postgraduate programs dominating its portfolio, and it has been ranked No. 1 for Engineering & Technology by the Higher Education Commission (HEC), Pakistan, in the three rankings it conducted (2006, 2012, 2013). The PIEAS Test case studies are 5 cases and about 2,548 words.
1BS Physics Lab: Thermal Conductivity and Heat Loss
A BS candidate measures the thermal conductivity of an aluminium alloy rod in a steady-state experiment. The rod is 300 mm long and 20 mm in diameter.
573 words, about 3 min2BS Chemistry Lab: Aspirin Yield and Limiting Reagent
A BS candidate prepares acetylsalicylic acid from 5.00 g salicylic acid (MW 138.12) and 8.0 mL acetic anhydride (density 1.08 g mL⁻¹, MW 102.09) with three drops of sulfuric acid. After recrystallization from ethanol–water, 4.10 g of dry product is obtained (MW 180.16).

A candidate in a numerical methods course solves f(x) = x³ − 2x + 2 = 0 with Newton–Raphson, starting at x₀ = 0. The first iterate is x₁ = 1.
504 words, about 3 min4MS/PhD Reactor Safety: Throughput Increase and Runaway Risk
A chemical engineering MS candidate reviews a proposal to increase throughput in a 2 m³ jacketed CSTR. The reactor processes an aqueous first-order exothermic reaction A → B.
525 words, about 3 min5MS/PhD CFD: Grid Convergence Versus Validation
An MS candidate simulates laminar flow over a backward-facing step at Re = 800 with a finite-volume code. The quantity of interest is the reattachment length x r/H.
