    To find the thermal boundary layer thickness, we can use the following equation:

    δ = 5.0 * x / sqrt(Re_x * Pr)

    where:
    δ = thermal boundary layer thickness
    x = distance along the plate (1.5 m in this case)
    Re_x = Reynolds number at x
    Pr = Prandtl number

    The Reynolds number can be calculated using the following equation:

    Re_x = (velocity * x) / kinematic viscosity

    where:
    velocity = velocity of the fluid (10 m/s)
    x = distance along the plate (1.5 m in this case)
    kinematic viscosity = 30 x 10^-6 m^2/s

    Let's calculate Re_x:

    Re_x = (10 * 1.5) / (30 x 10^-6)
    Re_x = 500000

    Now, we can calculate the thermal boundary layer thickness:

    δ = 5.0 * 1.5 / sqrt(500000 * 1)
    δ ≈ 0.021 m

    Therefore, the thermal boundary layer thickness is approximately 0.021 m.

    Concept:
    Since in question not any velocity profile is given so we will use Blasius equation.
    Calculation: 
    Pr = 1, T = 500 K, L = 1.5 m, T = 300 K

    ∵ Re ≤ 5 × 105
    ∴ Flow is laminar flow
    ∴ Blasius equation for laminar flow

    δhy = 6.12 mm
    δhy = δth = 6.12 mm
