Explanation:
Answer1-The specific latent heat of a substance is the quantity of heat energy required to change the state of a unit mass of a substance. EL=ml where EL is the heat transferred, in joules, m is the mass, in kilograms, and l is the latent heat in joules per kilogram. The SI unit for specific latent heat is Jkg−1.
Answer 2- The unit of viscosity is newton-second per square metre, which is usually expressed as pascal-second in SI units.
Answer 3- Derivation Of Continuity Equation
The continuity equation is defined as the product of cross-sectional area of the pipe and the velocity of the fluid at any given point along the pipe is constant. ...

Δm1= Density × Volume.
=> Δm1 = ρ1A1v1Δt ——–(Equation 1)
answer 4-The main difference between surface tension and surface energy is that surface tension measures the force per unit length of the surface while surface energy measures the amount of work that needs to be done per unit area in order to stretch it
answer 5-Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in static pressure or a decrease in the fluid's potential energy. To prove Bernoulli's theorem, consider a fluid of negligible viscosity moving with laminar flow
answer 6-Young's modulus is a measure of the ability of a material to withstand changes in length when under lengthwise tension or compression. Sometimes referred to as the modulus of elasticity, Young's modulus is equal to the longitudinal stress divided by the strain ( equations solve by your own)
answer 7-The velocity of efflux is the velocity with which a liquid will come out of a hole carved at some height from the bottom of the container in which the liquid is fille.The initial speed of efflux of the liquid at the hole is given as v={2(xH−4h)g} .
Stokes law- Stokes' law is a law in physics that states that the force that resists a sphere's fall in a viscous fluid is directly proportional to the velocity of the sphere, the radius of the sphere, and the viscosity of the fluid. ... r is the radius of the sphere.
three modes of heat transfer-The three types of heat transfer
Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own
