8. If the specific volume of a flow doubles, how will the flow’s mass flow rate change (double, quadruple, halve, etc.) assuming all other flow properties remain the same?

Answer #1

Specific volume is Volume per unit mass.

Specific volume=Volume/mass flow rate so if specific volume is double then. New specific volume will be double of initial specific volume.

New sp. Volume= 2*old sp. Volume.

Volume remain same(assume all other properties remain same) then. New mass flow rate will be,

New mass flow rate=Volume/new specific volume=Volume/2*old sp. Volume

So new mass flow rate will be =Old mass flow rate/2.

So mass flow rate become half while other properties remain same.

4. A liquid of specific gravity 0.9 flows through a rectangular notch at a mass flow rate of 585 Kg per second. Take Cd = 0.7 i) If the width of the notch should not exceed double the head of flow, then find head over the notch. (2.5 marks) ii) For the same discharge if the head over the notch is doubled then find the width of the notch. (2.5 marks)

Darcy's law gives us the volume flow rate-volume per time (for example, cubic meters per day, m^3/day). Another way to express volume is on a per-unit-area basis. For example, if we have a 1-m^3 cube, we know its base is 1 m^2 the cross-sectional area of the cube-and its height is 1m. If we fill the cube with water, we can say we have 1m of water per unit area. Darcy's law can be rearranged to calculate the volume flow...

Oil enters a counterflow heat exchanger at 600 K with a mass flow rate of 10 kg/s and exits at 350 K. A separate stream of liquid water enters at 20°C, 5 bar. Each stream experiences no significant change in pressure. Stray heat transfer with the surroundings of the heat exchanger and kinetic and potential energy effects can be ignored. The specific heat of the oil is constant, c = 2 kJ/kg · K. If the designer wants to ensure...
