Which of the statements are true?Group of answer choicesFor flow in a pipe, the velocity is the same across the pipe cross section.Mass flow rate can be defined as the multiples of density, pipe average velocity, and cross section area normal to the velocity.A volume flow rate is defined as the volume of the fluid flowing through a cross section per unit time.A mass flow rate into control volume is proportional to the velocity component parallel to the cross sectional area.Mass flow rate is defined as the amount of mass flowing through a cross section per unit time.

Considering the form of conservation mass: V1A1=V2A2, then which of the following statements is FALSE?a) This form of conservation of mass applies for the situation of constant densityb) This applies when there is one inlet but more than 1 outletc) This applies when the inflow and outflow velocities are uniformd) This applies for a steady flow

A cold-water stream at 400C and 100 kPa enters a mixing chamber with a mass flow rate of 0.46 kg/s, where it is mixed with a stream of hot water at 900C and 300 kPa. If the mixture is desired to leave the chamber at 500C and 275 kPa, determine the mass flow rate of the mixture stream in kg/s.
