There are approximately 15 milliliters (ml) in 1 tablespoon (tbsp). which expression can be used to find the approximate number of milliliters in 3 tbsp?

Answer : The approximate number of milliliters in 3 tbsp will be, 45 milliliters

Explanation :

Using the unitary method :

According to the question,

As, 1 tablespoon is present in 15 milliliters

So, 3 tablespoon is present in

Therefore, the approximate number of milliliters in 3 tbsp will be, 45 milliliters

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
