Ques 27 GATE 2011
A low speed wind tunnel has a contraction ratio of 14:1 and the cross-sectional area of the test
section is 1 m2. The static pressure difference between the settling chamber and the test section is
40 cm of water column. Assume g=9.81 m/s2, ρair=1.2 kg/m3 and ρwater=1000 kg/m3. The
speed of air in the test section (in m/s) is
Ques 28 GATE 2011
Consider the inviscid, adiabatic flow of air at free stream conditions, M1=2 p1=1 atm and T1=
288 K around a sharp expansion corner (θ=20o) as shown below. The Prandtl-Meyer function, v,
is given as a function of Mach number, M, as
expansion corner is approximately
Ques 29 GATE 2011
Consider a steady two dimensional zero-pressure gradient laminar flow of air over a flat plate as
shown below. The free stream conditions are U∞=100 ms-1 ρx=1.2 kgm-3, pα=1 atm and
μ∞=1.8×10-5 kgm-1s-1. The ratio of displacement thickness to momentum thickness of the
boundary layer at a distance of 2 m from the leading edge is

A student attempted to solve a quadratic equation in x twice. However, in the first attempt, he
incorrectly wrote the constant term and ended up with the roots as (4, 3). In the second attempt, he
incorrectly wrote down the coefficient of x and got the roots as (3, 2). Based on the above
information, the roots of the correct quadratic equation are
