The first bit is the sign bit. It's 0 for positive numbers and 1 for negative numbers.
The next 8-bits are for the exponents.
The first 0-126₁₀ (0-2⁷⁻¹) are for the negative exponent 2⁻¹-2⁻¹²⁶.
And the last 127-256₁₀ (2⁷-2⁸) are for the positive exponents 2⁰-2¹²⁶.
You have 1.25₁₀ which is 1.010₂ in binary. But IEEE wants it in scientific notation form. So its actually 1.010₂*2⁰
The exponent bit value is 127+0=127 which is 01111111 in binary.
The last 23-bits are for the mantissa, which is the fraction part of your number. 0.25₁₀ in binary is 010₂... so your mantissa will be:
010...00000000000000000000
Answer:
Kindly check Explanation section.
Explanation:
NB: please check the attachment for the solution to: the boundary layer thickness, the displacement thickness, the momentum thickness the wall shear stress, the friction coefficient, and the drag coefficient for a flat plate with zero pressure gradient in a laminar flow.
===============================
So,for the solution the second part of the question that asked us to state;
What happens if we add a constant positive pressure gradient?
SOLUTION: Whenever we have dp/dx > 0 that is a positive pressure gradient then, we are going to have what is known as a divergent flow which makes pressure to increase in the direction of flow. The pressure will be minimum around the centre. Also, as the velocity decreases(velocity gradient becomes negative), the area of flow increases.
