Discharge
The volume of liquid passing through a given cross-section in unit time is
called the discharge. It is measured in cubic meter per second (m³/s) , or similar units
and denoted by Q.
The formula is;
Q=AV
Contohlah, dia bagi Q=1 m³/s dia macam satu tangki yang setinggi meja, dia boleh buang air tu dalam masa satu saat.
Kalau dia bagi Q= 2m³/s dia macam dua tangki boleh buang air yang yang dalam tangki tu dalam satu saat je. Ha camtu lah.
Discharge ni, dia kira dari segi volume.
Kalau tangki air yang biasa kat rumah kita tu, biasanya dalam anggaran 0.001 m³/s. Kalau air slow tu dia macam dalam anggaran 0.0001 m³/s.
Oh pastu nak cari area tu, kalau dia bagi diameter pakai formula
A= (πd²)/4 // π(d/2)² ** sama je ni dua-dua
Kalau dia bagi radius, pakai formula
A=πr²
Mass flowrate
The mass of fluid passing through a given cross section in unit time is called
the mass flow rate. It is measured in kg/s and denoted by ṁ.
The formula is ;
ṁ=ρAV or ṁ=ρQ
where the ρ is density.
Mass flowrate ni pula, dia kira dari segi jisim .
